Self-Clinching Nuts
Self-Clinching Nuts are internally threaded fasteners designed for permanent installation in thin sheet metal, aluminum, and stainless steel panels. These nuts are pressed into pre-punched holes, where they displace surrounding material to form a secure, torque-resistant hold, eliminating the need for welding or loose fasteners.
At Rajal Industries, we manufacture precision-engineered Self-Clinching Nuts conforming to ISO and industry-specific standards, ensuring high pull-out resistance, long-term durability, and seamless integration in metal fabrication and electronic enclosures.

- Heat-Treated for Maximum Strength –Self-clinching nuts undergo precision hardening for enhanced press-fit retention and vibration resistance.
- Load Ratings Based on Material & Application:
- Carbon Steel Class 8 Self-Clinching Nut: 800-900 MPa tensile strength
- Stainless Steel A4-80 Self-Clinching Nut Nut: 700-800 MPa corrosion-resistant strength
Self-Clinching Nut Design & Engineering Features
Permanent Installation with High Retention Strength
- Embeds securely into metal panels with high push-out and torque resistance.
- Prevents loosening even under heavy vibration and repeated disassembly.
Optimized for Thin Sheet Metal Applications
- Requires minimal installation space, making it ideal for compact assemblies.
- Eliminates the need for welding, thread tapping, or additional locking features.
Various Self-Clinching Nut Designs for Different Applications
- Standard Self-Clinching Nuts (ISO 13599) – Provide high torque resistance in thin sheet metal.
Flanged Self-Clinching Nuts – Distribute load over a larger area for enhanced pull-out strength.
Blind Self-Clinching Nuts – Used in sealed enclosures to prevent fluid or debris ingress.
Compatible with Multiple Panel Materials & Thicknesses
- Designed for steel, stainless steel, aluminum, and soft alloy panels.
Ideal for 0.5mm to 3mm thick sheets, depending on the nut size.
Easy Installation with Minimal Equipment
- Can be installed using a hydraulic press, pneumatic press, or manual press tools.
Thread Specifications & Precision Engineering
| Thread Type | Description | Application |
|---|---|---|
| Coarse Thread (UNC/Metric) | Ensures fast engagement and strong grip | Electronics, enclosures, sheet metal assembly |
| Fine Thread (UNF/Metric Fine) | Provides higher tensile strength & precise load distribution | Aerospace, automotive, precision instruments |
| Fully Threaded Self-Clinching Nuts | Allows maximum engagement and secure fastening | Electrical enclosures, telecom cabinets |
| Partially Threaded Self-Clinching Nuts | Offers better clamping force & torque resistance | Metal fabrication, industrial machinery |
Thread Fitment & Compliance
- Metric threads conform to ISO 6H tolerances, ensuring secure engagement with mating components.
- Imperial self-clinching nuts meet ISO 13599 for universal compatibility.
Common Applications of Self-Clinching Nuts
- Electronics & PCB Enclosures – Provides secure fastening in thin-walled metal enclosures and circuit boards.
- Sheet Metal Fabrication & HVAC Systems – Ensures strong, vibration-resistant fastening in steel and aluminum panels.
- Automotive & Aerospace Engineering – Used in aircraft panels, vehicle interiors, and battery enclosures.
- Telecommunications & Electrical Cabinets – Ensures high-strength fastening in control panels and network enclosures.
- Medical Devices & Industrial Equipment – Provides strong, secure fastening in diagnostic instruments and machinery enclosures.
