TriPress® – Reduces assembly time by up to 75 %

Innovative Fastening and
Engineering Solutions

TriPress® is a triangular quick fastening system that can be clinched into plastic, light met-
als and steel. You can join two components quickly and economically by pressing in the
TriPress® fastener.

Technology in application

The TriPress® is available in the following designs:
   triangular shank and axially parallel knurls provide high
   torsional strength
   circumferential locking flutes on triangular shaft generate
   high pull-out resistance
   combinations of flutes and knurls create positive-fit fasten-
   ings and achieve high torsional torques and pull-out forces

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

                                                                    RAA axially    Circumferential  Flutes / knurl
