Application and function

Suitable for: Sheet metal with a tensile strength of less than 600N/mm²; can be used in galvanized, painted sheet metal

Sheet metal bottom: Flat without indentation, optimal fastening characteristics (clamping with a large surface area)

Pilot hole preparation: Pre-punched pilot hole according to AUTORIV specifications

Die: Use of a flat die (optimal downtimes)

Functionality: Torque absorbers move and shape the material into the collar undercut

Outer diameter - pull through force: Small outer diameter as standard for use in limited installation space. Outer diameter can be configured for specific application

Under-head serration - torque: Under-head knurls for high torque absorption

Collar - push out force: Collar with undercut to provide push out forces

ASN clinch nut clinching fastener Cross Section Detail
Cross section - ASN clinch nut in sheet metal


  • Lighter C-frame on the robot
  • Larger projections / overhangs possible
  • Shorter cycle times
  • Pressing into undercuts or profiles is easier to handle than with other fasteners

Lower risk of warping of workpieces, especially with many setting positions

  • Lower risk of warping of work pieces
  • Flat sheet metal bottom with largest surface possible for the preload through tightening

Greater compensation possible with custom design

  • Ensuring optimal pressing: No "NOK pressings" with risk of subsequent complaints and quality costs
  • No frequent re-teaching of the robot necessary
  • Ensuring high availability and output, thus cost reduction

Setting in limited installation spaces is possible
