General Information
The rivet nut, often also referred to as a self-clinching rivet nut, is a clinch fastener that is riveted into thin sheet metal to provide a thread for fastening screws.
The rivet nut is fastened by inserting it into a prefabricated pilot hole in the sheet metal and then forming the rivet collar on bottom of the sheet. As the formed rivet collar protrudes minimally on the back of the sheet metal, the pilot hole is provided with embossing.
Rivet nuts are highly resilient and are also suitable for lightweight construction, gas- and watertight applications and as an ideal replacement for weld nuts.

Application and Function
Suitable for: Insertion in metal sheets with tensile strength less than 800N/mm², water-tight and gas-tight applications
Sheet metal bottom: Indentation on sheet metal bottom. The rivet collar is approx. 0.2mm behind sheet metal bottom
Pilot hole preparation: Pre-punched pilot hole with embossing according to AUTORIV specifications
Die: Use of a special rivet die. Rivet collar or die should be oiled
Installation: The rivet collar is formed and folded over the sheet metal. The wedge under-head ribs are pressed into the sheet metal during the setting process
Outer diameter - pull through force: Very large outer diameter, well suited for aluminum applications, extremely high pull through force
Under-head serration - torque: Wedge under-head ribs for high torque absorption, especially in higher-strength metal sheets
Collar - push out force: Formable rivet collar that folds over the sheet metal and provides a very high push out force
Highlights
Highest possible torque and push out forces, better than with clinch nuts or self-piercing nuts
Customized solutions for sheet thicknesses above 3mm possible
- No diversity, less stock requirement
- No risk of mix-up (Incorrect fasteners in incorrect application)
- (Re-)use of existing automation / tooling, thus reduction of investment
- Suitable for sheet metal tensile strengths where conventional clinching fasteners or self-piercing nuts can not be used, from 600Mpa to approx. 800Mpa limit
- For custom applications, sheet metal with tensile strength from 800Mpa to 1,400 Mpa or higher is suitable
