Cage Nuts
Cage Nuts are square or rectangular nuts enclosed in a spring steel cage, designed to provide secure fastening in panel mounting, server racks, telecommunications, and industrial enclosures. The flexible cage allows easy insertion into pre-punched holes, enabling a floating nut that accommodates misalignment and reduces installation stress.
At Rajal Industries, we manufacture precision-engineered Cage Nuts conforming to DIN and general fastening standards, ensuring high load-bearing capacity, easy installation, and durable performance.
Sizes & Standards
| Size Range | Standards |

| Varies by application, based on nut size | DIN 267-28 – Standard for cage nuts used in industrial mounting applications |
| General nut standards for structural and panel fastening | |
Material & Strength Grades
| Material Type | Available Strength Grades | Industry Standards |
|---|---|---|
| Carbon Steel & Mild Steel | Class 4, 5, 8, 10 | DIN 267-28, General Nut Standards |
| Stainless Steel (Corrosion Resistant) | A2-70 (SS 304), A4-80 (SS 316) | ISO 3506 |
| Zinc-Plated Steel (Anti-Corrosion Coating) | Class 4, 5 | DIN 267-28 |
- Heat-Treated for Maximum Strength –Cage nuts undergo quenching and tempering for enhanced load capacity and durability.
- Load Ratings Based on Material & Application:
- Carbon Steel Class 8 Cage Nut: 800-900 MPa tensile strength
- Stainless Steel A4-80 Cage Nut Nut: 700-800 MPa corrosion-resistant strength
Cage Nut Design & Engineering Features
Floating Nut in a Retaining Cage for Easy Alignment
- The spring steel cage allows slight movement, ensuring easy bolt alignment during assembly.
- Enables fast installation and repositioning without reworking panel holes.
Multiple Cage Nut Variants for Different Applications
- Standard Cage Nuts (DIN 267-28) – Provide strong, vibration-resistant fastening in pre-punched panels.
- Captive Cage Nuts – Offer secure retention and prevent accidental loss.
- Heavy-Duty Cage Nuts – Designed for high-load applications in industrial equipment and racking systems.
Optimized for High-Torque & Vibration Resistance
- Provides consistent, high-load clamping force without deforming the mounting surface.
Ideal for repeated use in environments requiring frequent component access.
Compatible with Various Mounting & Fastening Systems
- Used with rack screws, machine screws, and structural bolts for secure panel attachment.
Designed for quick insertion and removal using standard tools or finger pressure.
Thread Specifications & Precision Engineering
| Thread Type | Description | Application |
|---|---|---|
| Coarse Thread (UNC/Metric) | Ensures quick engagement and strong grip | Server racks, enclosures, industrial panels |
| Fine Thread (UNF/Metric Fine) | Provides higher tensile strength & precise load transfer | Aerospace, precision engineering |
| Fully Threaded Cage Nuts | Allows maximum engagement and secure fastening | Electronics, telecommunications |
| Partially Threaded Cage Nuts | Offers better clamping force & structural strength | Automotive, railway, heavy machinery |
Thread Fitment & Compliance
- Metric threads conform to ISO 6H tolerances, ensuring secure engagement and torque resistance.
- Imperial cage nuts meet DIN 267-28 for industrial and electronic enclosure applications.
Common Applications of Cage Nuts
- Server Racks & Data Centers – Provides secure fastening for rack-mounted equipment and IT enclosures.
- Telecommunications & Electrical Panels – Ensures secure installation of network components and power enclosures.
- Automotive & Aerospace Engineering – Used in vehicle chassis, aircraft frames, and industrial enclosures.
- Railway & Infrastructure Projects – Ensures vibration-resistant fastening in train compartments and metro systems.
- Medical Devices & Precision Instruments – Fastens diagnostic equipment, control panels, and laboratory enclosures.
