Rapid Fastening System - Clinch Pin

TriPress(R) is a triangular rapid fastening system that can be clinched into plastic and light metals. During the clinching operation, the two components of the TriPress(R) fastener connect together quickly and economically.

It is available in the following designs:

Triangular shank and knurl parallel with axis provide greater torsional strength.
Circumferential locking flutes on triangular shaft generate high pull-out resistance.
Combination of grooves and knurls permit positive-fit fastenings and achieve high torsional torques and pull-out forces (figure 4).
So the fastener can be clinched into pre-prepared holes or injected as inserts into plastic housings.
