Rivet Nuts
Rivet Nuts, also known as blind rivet nuts or threaded inserts, are internally threaded fasteners designed for high-strength attachment in thin-walled materials such as sheet metal, plastics, and composite panels. These nuts provide permanent, vibration-resistant threading where traditional tapping or welding is impractical.
At Rajal Industries, we manufacture precision-engineered Rivet Nuts conforming to ISO and general fastening standards, ensuring superior grip strength, quick installation, and long-term durability.
Sizes & Standards
| Size Range | Standards |
|---|---|
| Metric: M2 to M10 | ISO 13599 – Standard for self-clinching nuts |
| Imperial: Gauge 4 to 12 | Manufacturer-specific standards for sheet metal fastening |
| General nut standards for metal fabrication applications |
Material & Strength Grades
| Material Type | Available Strength Grades | Industry Standards |
|---|---|---|
| Carbon Steel & Mild Steel | Class 4, 5, 8, 10 | ISO 15983, General Nut Standards |
| Stainless Steel (Corrosion Resistant) | A2-70 (SS 304), A4-80 (SS 316) | ISO 3506 |
| Aluminum Alloy (Lightweight Fastening) | Custom Hardness Ratings | ISO 15983 |
- Heat-Treated for Maximum Strength –Rivet nuts undergo precision hardening for enhanced load-bearing and pull-out resistance.
- Load Ratings Based on Material & Application:
- Carbon Steel Class 8 Rivet Nut: 800-900 MPa tensile strength
- Stainless Steel A4-80 Rivet Nut: 700-800 MPa corrosion-resistant strength
Rivet Nut Design & Engineering Features
Threaded Inserts for Secure Fastening in Thin Materials
- Provides strong internal threads in thin sheets, plastics, and composites.
- Enables bolt attachment without requiring tapped holes or back access.
Multiple Rivet Nut Variants for Different Applications
- Standard Open-End Rivet Nuts (ISO 15983) – Provide high pull-out resistance for general use.
Closed-End Rivet Nuts – Prevent fluid or debris ingress in sealed enclosures.
Hexagonal & Knurled Rivet Nuts – Offer anti-rotation locking in high-vibration environments.
Flanged Rivet Nuts – Distribute load over a wider area, reducing stress on thin materials.
Fast Installation with Minimal Equipment
- Installed using hand, pneumatic, or hydraulic rivet nut tools.
Requires only access from one side (blind installation), making it ideal for enclosed spaces.
High Load-Bearing Capacity & Vibration Resistance
- Provides secure threading without risk of loosening under dynamic forces.
Ensures long-term fastening in automotive, aerospace, and industrial applications.
Thread Specifications & Precision Engineering
| Thread Type | Description | Application |
|---|---|---|
| Coarse Thread (UNC/Metric) | Ensures fast engagement and strong grip | Automotive, aerospace, industrial assembly |
| Fine Thread (UNF/Metric Fine) | Provides higher tensile strength & precise load transfer | Electronics, railway, machinery |
| Fully Threaded Rivet Nuts | Allows maximum engagement and secure fastening | HVAC, enclosures, panel fastenings |
| Partially Threaded Rivet Nuts | Offers better clamping force & structural strength | Power plants, industrial fabrications |
Thread Fitment & Compliance
- Metric threads conform to ISO 6H tolerances, ensuring secure engagement with mating bolts.
- Imperial rivet nuts meet ISO 15983 for universal compatibility.
Common Applications of Rivet Nuts
- Automotive & Aerospace Engineering – Provides threaded fastening in vehicle bodies, aircraft panels, and engine compartments.
- Electronics & Enclosures – Ensures secure fastening in circuit boards, control panels, and instrument enclosures.
- Railway & Transportation Infrastructure – Used in rail carriages, metro trains, and transport systems.
- HVAC & Sheet Metal Fabrication – Provides high-strength attachment in air ducts, ventilation systems, and metal panels.
- Medical Devices & Industrial Machinery – Fastens diagnostic equipment, heavy machinery covers, and robotic systems.
