Rivet Nut Manufacturer in India for Sheet Metal, Automotive & Industrial OEMs

Choosing the right Rivet Nut Manufacturer is important when an OEM needs a reliable internal thread in thin sheet, hollow sections, tubes or assemblies where the rear side is difficult or impossible to access.

A rivet nut is a threaded insert installed into a prepared hole from one accessible side. During installation, the body deforms on the blind side of the parent material and mechanically locks the insert into position.

The result is a reusable female thread for a mating screw or bolt.

Rivet nuts are commonly considered for applications such as:

Automotive components
EV battery-related structures and enclosures
HVAC equipment
Electrical cabinets
Electronics
Appliances
Machinery covers
Sheet-metal assemblies
Hollow profiles
Industrial enclosures

Current manufacturer ranges show rivet nuts with cylindrical/round, knurled, hexagonal and half-hexagonal bodies, multiple head styles, open or closed ends and materials including steel, aluminium and stainless steel. (FAR)

The correct product depends on much more than thread size.

A better selection sequence is:

Application → Parent Material → Sheet Thickness → Hole → Grip Range → Body Style → Head Style → Thread → Material → Finish → Installation Tool → Performance Requirement → Testing

Quick Answer: What Is a Rivet Nut?

A Threaded Rivet Nut is a mechanically installed threaded insert that creates a female thread in sheet, hollow sections or other suitable parent material.

Unlike a conventional nut, access to the back side is generally not required for installation.

The insert is placed into a prepared hole and a setting tool causes part of its body to deform behind the parent material, mechanically retaining it.

This is why rivet nuts are also commonly called:

Blind rivet nuts
Blind threaded inserts
Rivnuts
Threaded inserts

Terminology varies between manufacturers and markets.

Why Do OEMs Use Rivet Nuts?

Thin sheet metal may not provide enough material thickness for a useful directly tapped thread.

A rivet nut provides a separate threaded insert.

It can also be useful where:

Back-side access is unavailable
Welding is undesirable
A reusable thread is required
The assembly uses hollow sections
The parent material is relatively thin
Production requires one-side installation
Dissimilar joining processes need to be considered

The actual suitability depends on the application.

How Does a Rivet Nut Work?

A simplified installation sequence is:

Prepare Hole → Insert Rivet Nut → Engage Setting Tool → Pull/Set Insert → Body Deforms Behind Sheet → Release Tool → Install Mating Screw

During setting, the rivet nut forms a mechanical grip around the parent material.

This creates a fixed threaded attachment point.

What Does “Blind Installation” Mean?

“Blind” means the installer can generally install the fastener from one accessible side of the workpiece.

The installer does not need to hold a conventional nut behind the sheet during installation.

This is particularly useful for:

Closed sections
Tubes
Box sections
Enclosures
Vehicle structures
Cabinets
Assembled panels

Blind threaded inserts are specifically used to create threads where the opposite side cannot conveniently be accessed. (Newport Fasteners)

Rivet Nut Anatomy

A typical rivet nut contains several functional areas.

Head or Flange

Seats against the visible side of the parent material.

Body

Passes through the prepared hole.

Deformation Zone

Changes shape during installation to grip the blind side.

Internal Thread

Accepts the mating screw or bolt.

Body Features

Depending on design, the body can be:

Smooth
Knurled/ribbed
Hexagonal
Half-hexagonal

Each feature affects installation and performance.

Rivet Nut vs Standard Nut

Feature	Standard Nut	Rivet Nut
Back-Side Access During Installation	Usually required	Generally not required
Creates Captive Thread	No	Yes
Thin Sheet Application	Requires access/support	Common application
Installation Tool	Spanner/socket	Rivet-nut setting tool
Parent-Material Hole	Clearance arrangement	Controlled installation hole
Removal of Mating Screw	Nut may need holding	Insert remains installed
Hollow Section Use	Difficult in many cases	Major advantage

Rivet Nut vs Weld Nut

Both can create a permanent threaded location in sheet-metal assemblies, but the installation process is very different.

Weld Nut

Requires a suitable welding process and compatible parent material.

Rivet Nut

Uses mechanical deformation and can generally be installed from one side.

Factor	Rivet Nut	Weld Nut
Joining Process	Mechanical	Welding
Heat Input	No welding heat	Welding heat
Blind-Side Access	Generally not needed	Process/design dependent
Installation Equipment	Setting tool	Welding equipment
Parent Material	Application dependent	Must be weld-compatible
Finished/Coated Panel	Can be advantageous in some cases	Welding can affect coating/process
Thread Replacement	Insert replacement possible but process-dependent	Welded component

Neither is universally better.

Rivet Nut vs Self-Clinching Nut

This is an important OEM comparison.

A self-clinching nut normally requires access for a press/anvil arrangement to squeeze the fastener into suitable sheet.

A rivet nut is specifically useful where installation is required from one side.

Factor	Rivet Nut	Self-Clinching Nut
Installation Access	One side	Press access/support required
Retention Method	Blind-side body deformation	Sheet flows into clinching feature
Hole	Product-specific	Product-specific
Sheet Compatibility	Product-specific	Hardness/thickness critical
Field Installation	Possible with suitable tooling	Usually manufacturing-stage press operation
Hollow Sections	Strong advantage	Often difficult
Reusable Female Thread	Yes	Yes

For a detailed comparison, buyers should also review the self-clinching nut selection guides.

Rivet Nut vs Tapped Sheet

Directly tapping thin sheet can provide limited thread engagement because the sheet thickness controls the available thread depth.

A Threaded Rivet Nut adds a dedicated threaded component.

This can be useful when the assembly needs:

Greater usable thread depth
Repeated screw removal
A more robust threaded location
Blind installation

The final joint strength still depends on the complete assembly.

Rivet Nut vs Cage Nut

A cage nut is normally retained mechanically in a compatible panel or rack opening and can provide limited floating movement.

A rivet nut is mechanically set into the parent material.

Therefore:

Cage Nut = Replaceable/Floating Thread Concept

Rivet Nut = Mechanically Set Blind Threaded Insert

The applications overlap only in certain assemblies.

Rivet Nut vs Threaded Insert

“Threaded insert” is a broad category.

A rivet nut is one type of threaded insert.

Other threaded inserts can be designed for:

Plastic
Wood
Castings
Machined components
Thread repair
Sheet metal

When requesting quotations, using blind rivet nut or threaded rivet nut helps make the required product clearer.

Main Rivet Nut Types

A Rivet Nut Manufacturer may offer several combinations of head and body style.

Common configurations include:

Round Smooth Body

Simple cylindrical body.

Round Knurled or Ribbed Body

Surface features help improve resistance to rotation in suitable applications.

Hex Body

Installed into a matching hexagonal hole to provide strong anti-rotation characteristics.

Half-Hex Body

Uses a partly hexagonal body and matching installation geometry.

Open-End Rivet Nut

Thread/body remains open through the end.

Closed-End Rivet Nut

The blind end is closed for applications requiring that configuration.

Current manufacturer catalogues confirm cylindrical, hexagonal and half-hexagonal body options, with cylindrical versions often using knurling to increase resistance to rotation. (FAR)

Round Body Rivet Nut

Round-body rivet nuts are widely used because the required mounting hole can generally be produced using conventional round-hole processes.

Possible body configurations include:

Smooth
Knurled
Ribbed

The correct design depends on required torque resistance and parent material.

Knurled Rivet Nut

A knurled or ribbed body provides additional engagement with the hole wall.

This can help improve resistance to rotation compared with some smooth round-body designs.

For example, current ribbed rivet-nut product data specifically identifies the splined body as improving torque-to-turn resistance. (Rivet Nuts)

However:

Knurled does not automatically mean the insert can never spin.

Performance still depends on:

Hole
Parent material
Grip range
Installation
Body geometry
Applied load

Hex Body Rivet Nut

A hex-body rivet nut fits into a matching hexagonal hole.

The flats mechanically resist rotation.

This can provide stronger anti-rotation behaviour than many round-body designs.

Current blind-rivet-nut manufacturers describe hexagonal and half-hexagonal bodies as specifically addressing rotation within the mounting hole. (FAR)

Hex Body Requires the Correct Hole

A hex rivet nut should not simply be installed into a normal oversized round hole.

The matching hole geometry is part of the retention system.

Therefore, the drawing should specify:

Hole shape
Across-flat dimension where applicable
Tolerance
Parent-material thickness
Rivet-nut body

The insert and hole must be engineered together.

Half-Hex Rivet Nut

A half-hex body combines hexagonal and cylindrical body sections.

It can be useful where the application requires increased anti-rotation performance and the product family supports that installation.

As with a full-hex design, hole preparation becomes an important manufacturing consideration.

Open-End Rivet Nut

An open-end rivet nut has an open body/thread end.

This is a common construction for many sheet-metal applications.

Check:

Screw length
Available blind-side clearance
Environment
Assembly design

before selection.

Closed-End Rivet Nut

A closed-end rivet nut has a sealed or closed bottom.

Current manufacturers offer open and closed blind-rivet-nut constructions. (FAR)

A closed-end design can be considered where the application benefits from preventing the mating screw from projecting through the insert or where a more closed assembly configuration is required.

Do not automatically describe every closed-end rivet nut as fully liquid- or pressure-tight unless the specific product and complete installed joint are validated for that requirement.

Rivet Nut Head Styles

The head or flange also changes how the insert interfaces with the panel.

Common styles include:

Large flange
Standard/flat head
Reduced head
Countersunk head

Current manufacturer catalogues list dome/standard, countersunk and reduced-head configurations. (FAR)

Large Flange Rivet Nut

A larger flange provides a larger bearing area against the visible surface.

This can be useful for suitable:

Thin sheet
Softer parent material
Larger bearing requirements

But the larger head also occupies more surface area.

Check:

Clearance
Appearance
Adjacent components

Reduced-Head Rivet Nut

A reduced head minimizes protrusion above the parent surface.

This can be useful where:

Clearance is limited
A lower profile is desired
Nearby components need more space

The smaller bearing area should still be appropriate for the parent material and load.

Countersunk Rivet Nut

A countersunk head can provide a more flush installation when used with the correctly prepared hole.

The countersink geometry must match the product.

Do not create an arbitrary countersink without checking the manufacturer’s or approved drawing dimensions.

Head Style Does Not Define Body Style

These are separate choices.

For example, a product can combine:

Reduced Head + Knurled Round Body

or:

Flat Head + Hex Body

Therefore, an RFQ should identify both.

What Is Rivet Nut Grip Range?

Grip range is one of the most important rivet-nut specifications.

It identifies the parent-material thickness range for which that particular insert is designed to set correctly.

Current product catalogues show that the same thread size can have multiple rivet-nut lengths for different grip ranges. (Rivet Nuts)

This means:

Thread size alone cannot select a rivet nut.

Why Grip Range Matters

Suppose two inserts both use an M6 thread.

One may be designed for a relatively thin panel.

Another may be designed for a thicker panel.

They are not automatically interchangeable.

If the actual sheet thickness falls outside the approved grip range, the insert may not deform and retain as intended.

Grip Range Is Not Thread Size

This distinction is critical.

Thread Size

Controls the mating screw.

Grip Range

Controls the parent-material thickness range.

A complete rivet-nut specification needs both.

Example of Product-Specific Grip Range

Current ribbed rivet-nut data illustrates the concept clearly.

Within one product family, an M6 × 1.0 version is offered for a 0.70–4.20 mm grip range and another M6 version for 4.20–6.60 mm. M8 and M10 versions in that family also use multiple grip ranges. (Rivet Nuts)

These are product-specific examples, not universal M6, M8 or M10 rivet-nut dimensions.

Always use the approved manufacturer’s data or customer drawing.

Sheet Thickness Must Be Known

An RFQ stating:

Need M6 rivet nut

is incomplete.

A better specification includes:

M6 × 1.0 rivet nut for specified sheet thickness/grip range, with required body, head, material and finish.

The Rivet Nut Manufacturer needs the parent-material thickness to select or develop the correct body length.

Hole Diameter Is Critical

The mounting hole directly affects installation.

If the hole is too small:

Insert may not enter
Coating may be damaged
Body can be forced or distorted

If the hole is too large:

Anti-rotation performance may decrease
Insert can move
Setting quality can suffer
Retention can be reduced

Use the hole size and tolerance specified for the actual product.

Do Not Calculate Hole Size From Thread Size

There is no universal rule such as:

M6 rivet nut = M6 hole.

The rivet-nut body must fit through the hole, so the mounting hole is larger than the internal thread and depends on the product design.

For example, one current round-body family lists an M6 × 1.0 insert with a 10.00 mm mounting hole, while another manufacturer’s M6 cylindrical product uses approximately a 9.1–9.2 mm hole. (Rivet Nuts)

That difference is exactly why the product drawing must control.

Rivet Nut Thread Sizes

Commercial rivet-nut ranges commonly cover several metric thread sizes.

One current manufacturer offers blind rivet nuts with threads from M3 to M12 depending on type. (FAR)

Other product families may have different ranges.

Possible OEM requirements include:

but this should not be treated as a universal manufacturing range.

Metric and Inch Rivet Nuts

Depending on manufacturer and market, rivet nuts can use:

Metric threads
UNC threads
UNF threads
Customer-specific threads

Current commercial ribbed rivet-nut ranges include both metric and Unified inch-thread versions. (Rivet Nuts)

The RFQ should clearly specify the thread system.

Rivet Nut Materials

Common material options include:

Steel
Stainless steel
Aluminium

Current blind-rivet-nut manufacturers offer combinations including aluminium, steel, A2 stainless and A4 stainless depending on the product family. (FAR)

Material selection should consider:

Parent Material + Mechanical Requirement + Setting Force + Corrosion + Weight + Environment + Mating Screw

Steel Rivet Nuts

Steel rivet nuts are widely used for industrial and sheet-metal applications.

Possible advantages include:

Mechanical capability
Availability
Multiple finishes
Cost effectiveness for suitable applications

The actual grade and mechanical requirements should be defined by the product specification.

Stainless Steel Rivet Nuts

Stainless steel can be considered where improved corrosion resistance is required.

Applications may include:

Outdoor equipment
Food-related equipment where appropriate
Industrial environments
Certain HVAC systems
Selected automotive or EV applications

However, stainless steel generally requires consideration of installation force and tooling as well as corrosion.

Do not select stainless only because it sounds “premium.”

Aluminium Rivet Nuts

Aluminium rivet nuts can be useful where:

Low weight is important
Parent material is aluminium
Lower setting force is beneficial
Corrosion/material compatibility supports the selection

The required mechanical performance still needs to be checked.

Rivet Nut Material Comparison

Material	Potential Advantage	Main Check
Steel	Strength + economical availability	Corrosion protection
Stainless Steel	Corrosion resistance	Setting/tooling + environment
Aluminium	Lightweight + lower setting effort	Mechanical requirement

This is a screening comparison, not a universal specification.

Rivet Nut Finish

Steel Sheet Metal Fasteners may use finishes such as:

Zinc-based coatings
Zinc-nickel
Other customer-specified surface treatments

Current manufacturers offer galvanized/zinc-treated steel rivet nuts and, in some cases, additional corrosion-resistant treatments such as zinc-nickel or Geomet-type systems. (Sariv)

The required finish should follow the OEM environment and corrosion specification.

Parent Material Compatibility

The parent material can include suitable:

Steel sheet
Stainless sheet
Aluminium sheet
Hollow sections
Profiles
Certain composites or plastics with suitable insert designs

Do not assume one standard rivet nut works equally well in all these materials.

Thin Sheet Applications

Rivet nuts are particularly useful where sheet thickness makes conventional tapping impractical or where back-side nut access is unavailable.

However, thin sheet can also be sensitive to:

Distortion
Pull-through
Local deformation

The head style, body design and installation setting must therefore suit the panel.

Rivet Nuts in Aluminium Sheet

When installing a rivet nut into aluminium, consider:

Parent-material strength
Sheet thickness
Hole quality
Insert material
Bearing area
Galvanic compatibility
Required torque/pull-out performance

Material combinations should be evaluated for the service environment.

Rivet Nuts in Stainless Sheet

For stainless parent material, check:

Hole production
Insert material
Installation force
Tool capacity
Corrosion requirements
Dissimilar-material considerations

Do not assume a stainless panel automatically requires a stainless rivet nut.

Rivet Nuts in Plastic or Composite Panels

Certain blind threaded inserts are specifically designed for softer or non-metallic parent materials.

For example, cross-nut/slotted-body designs spread into multiple legs and provide a wider blind-side bearing area for suitable thin sheet and plastic applications. (Rivet Nuts)

A standard metal-sheet rivet nut should not automatically be used in plastic without validation.

Rivet Nut Installation Tools

A rivet nut requires suitable setting equipment.

Possible production systems include:

Manual tools
Pneumatic tools
Pneumatic-hydraulic tools
Hydraulic systems
Battery/electric tools
Automated production equipment

Tool selection depends on:

Rivet-nut size
Material
Production volume
Accessibility
Required process control

Pull-to-Stroke vs Pull-to-Force Concepts

Industrial rivet-nut tooling can use different setting-control strategies.

The important point for OEM buyers is:

The setting process must match the rivet nut and parent material.

Too little setting can result in inadequate retention.

Too much setting can damage:

Insert
Thread
Parent sheet
Tool mandrel

The approved rivet-nut/tool process should control installation.

Do Not Use a Generic Installation Force

There is no safe universal statement such as:

All M6 steel rivet nuts require X kN.

Installation depends on:

Product geometry
Material
Grip range
Parent material
Tooling
Manufacturer specification

Use validated product data.

Rivet Nut Performance Requirements

Depending on the application, OEMs may evaluate:

Torque Resistance

Resistance to the installed insert rotating in the parent material.

Push-Out / Pull-Out Behaviour

Resistance to displacement from the installed panel under the specified test condition.

Thread Performance

Ability of the internal thread to perform as specified.

Installation Quality

Correct deformation and seating.

These characteristics are product- and application-specific.

Torque-Out Is Not Screw Tightening Torque

This distinction is critical.

Torque-Out / Spin Resistance

Measures resistance of the installed insert to rotating in the parent material under a defined test.

Screw Tightening Torque

Relates to tightening the mating screw and forming the bolted joint.

They are not the same value.

Do not use a rivet-nut torque-out value as a universal screw-tightening torque.

Pull-Out Is Not Complete Joint Strength

Similarly:

Insert Pull-Out Performance

Describes a particular insert/parent-material test.

Final Joint Strength

Depends on:

Screw
Insert
Sheet
Bracket
Load direction
Geometry
Installation

Do not treat a catalogue pull-out value as the capacity of the entire assembly.

Why Body Style Affects Rotation Resistance

When a mating screw is tightened, torque is transferred into the installed insert.

The insert must resist rotating in the panel.

Anti-rotation can be influenced by:

Body shape
Knurling
Hole geometry
Parent material
Installation quality

Hex-body designs use geometric engagement, while knurled round bodies use surface interaction with the hole.

Why the Head Matters

The head helps provide bearing against the visible side of the sheet.

Its design influences:

Bearing area
Protrusion
Appearance
Clearance
Parent-material interaction

Do not select a reduced head solely for appearance if the application requires a larger bearing area.

Automotive Rivet Nut Applications

Potential automotive uses can include:

Body structures
Brackets
Interior mounting
Underbody components
Equipment mounting
Sheet-metal assemblies

Actual fastener selection depends on the OEM drawing and vehicle requirements.

Rivet Nuts for EV Applications

EV assemblies can contain:

Battery-related enclosures
Electronics housings
Brackets
Covers
Sheet-metal structures

Blind threaded inserts can be useful where one-side access and removable bolted components are required.

However, EV applications may introduce additional requirements for:

Corrosion
Sealing
electrical considerations
lightweight materials
traceability
automation
OEM validation

These should be defined by the customer.

Rivet Nuts for HVAC

Potential HVAC applications include:

Sheet-metal cabinets
Duct equipment
Frames
Covers
Service panels
Equipment housings

Rivet nuts can create reusable threaded locations without requiring a loose nut behind the sheet.

Rivet Nuts for Electronics

Electronics applications can include:

Enclosures
Racks
Equipment housings
Mounting panels
Brackets

Important selection factors include:

Sheet thickness
available space
head profile
thread size
installation access
corrosion/finish

Rivet Nuts for Appliances

Potential uses include:

Cabinets
Frames
Service panels
Internal brackets
Equipment mounts

Production-volume appliances can place additional importance on:

Installation cycle
repeatability
tool life
automated feeding
cost per installed joint

Rivet Nuts for General Sheet Metal

A rivet nut can be useful when the design needs:

Thin Sheet + Reusable Thread + One-Side Installation

This is one of the most important application combinations for the product family.

Rivet Nuts in Hollow Sections

Hollow profiles are a major application because installing a conventional nut inside the section may be impossible after fabrication.

The rivet nut can be installed from the accessible outer surface.

Potential examples include:

Tubular frames
Box sections
Equipment structures
Fabricated profiles

Common Rivet Nut Failure: Insert Spins

An installed rivet nut may rotate when the mating screw is tightened.

Possible causes include:

Oversized hole
Wrong body style
Incorrect grip range
Under-setting
Parent-material issue
Insufficient anti-rotation feature

Do not immediately blame the nut without checking the hole and installation process.

Common Failure: Insert Pulls Out

Possible causes include:

Wrong grip range
Weak/thin parent material
Incorrect head/body selection
Poor setting
Oversized hole
Excessive application load

The complete assembly needs investigation.

Common Failure: Sheet Distortion

Possible causes include:

Excessive setting
Very thin sheet
Inappropriate head/body design
Tool setup
Parent-material weakness

The setting process should be optimized using representative production material.

Common Failure: Thread Damage

Possible causes include:

Setting-tool mandrel problem
Over-setting
Poor thread manufacture
Coating interference
Wrong mating screw
Cross-threading

Thread inspection should be part of production control.

Common Failure: Rivet Nut Is Loose After Setting

Possible causes include:

Under-setting
Wrong grip range
Oversized hole
Incorrect insert length
Wrong product
Parent-material variation

Measure the actual sheet before changing tool settings.

Common Failure: Head Does Not Seat Properly

Investigate:

Hole burr
Hole deformation
Incorrect countersink
Damaged flange
Misaligned installation tool
Contamination
Wrong product

Good installation starts with good hole preparation.

Manufacturing Rivet Nuts

A typical manufacturing flow can include:

Raw Material → Forming/Machining → Body Features → Thread Formation → Heat/Material Processing if Required → Surface Treatment → Dimensional Inspection → Thread Inspection → Functional Setting Test → Packing

The exact process depends on rivet-nut design, material and production volume.

Why Body Geometry Requires Control

The body must deform in a controlled way during installation.

Important characteristics can include:

Wall thickness
Body diameter
Body length
Deformation-zone geometry
Knurling
Hex dimensions
Head dimensions

Variation in these characteristics can affect installation.

Thread Manufacturing

The internal thread must correctly engage the setting-tool mandrel and later the customer’s mating screw.

Quality control should consider:

Thread diameter
Pitch
Tolerance
Damage
Surface treatment

Thread quality is particularly important because the installation tool itself engages the thread.

Hole Preparation Quality

The OEM process should control:

Hole diameter
Hole shape
Burr
Roundness
Position
Surface condition

For hex-body inserts, hole geometry becomes even more important.

Functional Setting Test

A Rivet Nut Manufacturer should not rely only on loose-part dimensional inspection.

A useful functional test uses a representative panel or controlled test coupon.

The test can check:

Insertion
Setting
Head seating
Blind-side deformation
Thread condition
Rotation resistance
Removal/pull performance where specified

Representative Sheet Testing

The best test coupon should represent the real application as closely as practical.

Consider:

Material
Thickness
Hole
Coating
Surface condition

An insert that works in a thick laboratory steel plate may behave differently in the customer’s thin aluminium production panel.

Rivet Nut Quality Control

A practical control plan can include:

Material Verification → Dimensions → Body Geometry → Thread → Finish → Hole/Grip Compatibility → Functional Setting → Torque/Push/Pull Testing as Required → Final Inspection → Packing

Important Inspection Characteristics

Characteristic	Why It Matters
Thread	Tool + mating screw compatibility
Body Diameter	Hole fit
Body Length	Grip range
Wall/Deformation Zone	Setting behaviour
Head Diameter	Bearing
Head Height	Clearance
Knurl/Hex Geometry	Anti-rotation
Material	Mechanical behaviour
Finish	Corrosion + fit

Rivet Nut Documentation for OEM Buyers

Depending on the project, buyers may request:

Material certificate
Dimensional inspection report
Thread inspection
Coating report
Functional installation report
Torque-out test
Push-out/pull-out test
Corrosion test
Lot traceability
PPAP documentation

Requirements should be agreed before production.

Automotive and EV PPAP Requirements

Automotive buyers may require a formal approval process.

Depending on customer requirements, this can include:

Approved drawing
Material data
Dimensional results
Process flow
Control plan
PFMEA
MSA
Capability studies
Sample approval
Traceability

The exact PPAP level and documentation should come from the customer.

Common Rivet Nut Buying Mistakes

Avoid:

Buying only by thread size.
Ignoring grip range.
Guessing hole diameter from thread size.
Ignoring sheet material.
Ignoring sheet thickness.
Selecting body style only by appearance.
Assuming knurled means it cannot spin.
Using a hex insert without a compatible hole.
Ignoring head clearance.
Ignoring installation-tool capacity.
Using generic setting-force values.
Confusing torque-out with screw tightening torque.
Treating pull-out as total joint capacity.
Approving only loose parts without setting trials.
Ignoring corrosion and material compatibility.

What Is a Rivet Nut?

A rivet nut is a blind threaded insert installed into a prepared hole from one accessible side. During setting, its body deforms behind the parent material and creates a retained female thread for a mating screw or bolt.

Why Use a Rivet Nut in Sheet Metal?

A rivet nut can create a reusable female thread in thin sheet where direct tapping may provide insufficient thread engagement or where a conventional nut cannot be accessed from the back side.

What Is Rivet Nut Grip Range?

Grip range is the parent-material thickness range for which a particular rivet nut is designed. The same thread size can be available in multiple body lengths and grip ranges, so sheet thickness must be known before selecting the insert. (Rivet Nuts)

What Is the Difference Between a Rivet Nut and a Rivnut?

Rivet nut and Rivnut are commonly used for the same general type of blind threaded insert. Buyers should still specify the actual thread, grip range, body style, head, material, finish and installation requirements rather than relying only on the product name.

Does a Rivet Nut Need Back-Side Access?

Generally, no. One of the main advantages of a blind rivet nut is that it can be installed from one accessible side of the workpiece, making it useful for hollow sections, enclosures and closed sheet-metal assemblies. (Newport Fasteners)

What Materials Are Rivet Nuts Made From?

Common rivet-nut materials include steel, aluminium and stainless steel. Current commercial ranges include aluminium, steel, A2 stainless and A4 stainless depending on the design. Material should be selected from mechanical, corrosion, setting and parent-material requirements. (FAR)

Which Is Better, Round or Hex Rivet Nut?

Neither is universally better. Round-body rivet nuts simplify hole production, while hex-body designs can provide stronger geometric resistance to rotation when installed in a correctly sized hexagonal hole. The application and manufacturing process should determine the choice. (FAR)

Can Rivet Nuts Be Used in Automotive and EV Applications?

Yes. Rivet nuts can provide blind-installed reusable threads for suitable automotive and EV sheet-metal assemblies. The OEM should define the parent material, grip range, hole, mechanical performance, corrosion requirements, installation process and approval documentation.

Can Rajal Industries Manufacture Rivet Nuts?

Rajal Industries can evaluate customer requirements for Threaded Rivet Nut and drawing-based Sheet Metal Fasteners for automotive, EV, HVAC, electronics, appliances and industrial sheet-metal applications.

A technical review should include:

Drawing + Thread + Parent Material + Sheet Thickness + Hole + Grip Range + Body Style + Head Style + Material + Finish + Mating Screw + Functional Requirement + Installation Process + Quantity

Custom or specialized rivet-nut requirements should be evaluated subject to technical feasibility, tooling, manufacturing process and sample validation.

Conclusion: Rivet Nut Performance Depends on the Installed System

Selecting a Rivet Nut Manufacturer should involve much more than asking for an M5, M6 or M8 threaded insert.

A reliable selection process is:

Application → Sheet Material → Thickness → Hole → Grip Range → Body → Head → Thread → Material → Finish → Mating Screw → Installation → Testing

For automotive, EV, HVAC, electronics, appliances and industrial sheet metal, the rivet nut must work with the actual parent material and production process.

A correctly manufactured Threaded Rivet Nut can still fail if the hole, grip range or setting process is wrong. Likewise, a good assembly process cannot compensate for an incorrectly manufactured insert.

Rajal Industries can evaluate drawing-based rivet nuts and custom Sheet Metal Fasteners for OEM requirements, subject to technical feasibility, tooling and sample validation.
