TriPress®

Rapid fastenings with self-clinching screws

This triangular rapid fastener system from ARNOLD can be pressed into plastics, light metals and steel to join two components quickly and economically.

Benefits

The triangular shape allows torsion torques which, compared with bolts with round knurls are around 35% higher – and also present higher vibration resistance, They are also particularly secure when fitting nuts with the TriPress® centre collar version (MB) and the TriPress® connecting fastener. The circumferential locking flutes ensure better pull-out forces and security against autonomous loosening.

Characteristics

TriPress® is supplied in different designs:

  • A triangular shank and axially parallel knurls provide high torsional strength
  • The circumferential locking flutes on the triangular shaft generate high pull-out resistance
  • A combination of flutes and knurls permit positive-fit fastenings, high torsional torques and pull-out forces

The fastener can be clinched into pre-prepared holes or injected as inserts into plastic housings.

Advantages

The advantages of TriPress® over screw fastenings:

  • 75% less installation time
  • No assembly errors
  • Independent of pre-stress forces
  • Force-controlled press-fit
  • Uses more economical operating materials and tools

 

The advantages of TriPress® over injection-fitted screws into plastics:

  • No need to insert metal parts into injection moulds
  • Shorter cycle times (injection moulding)
  • No lost fastener elements
