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: Medium outer diameter, also suitable for aluminum applications, good 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

Highest possible torque and push-out forces, better than with clinch nuts or self-piercing nuts

Customized solutions for sheet thicknesses above 3mm possible

  • 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
