Self -Tapping / Threading Thread inserts for critical applications

The standard brass self-tapping Trisert® range has for many years included three primary designs: Double Ended, Reduced Headed and Regular Headed variants. These solve most application problems in thermoset and thermoplastic grades, including the latest engineering plastics.
Trisert-3® is the latest addition to this family and has been developed to expand the proven Trisert® range into more critical applications including light metal alloys: aluminium, magnesium as well as glass-filled thermoplastics and epoxy / hard-glass thermosets possibly incorporating carbon & kevlar-fibre reinforcement. ONLY TAPPEX HAVE DESIGNED A SELF-TAPPING INSERT WITH BESPOKE CURVED CUTTING FEATURES – WATCH OUT FOR COPIES FROM ASIA AND THE UK!
The concept of the Trisert-3® design is to provide efficient installation of threaded inserts into post-mould & machined parts especially as the installation torque can be more precisely controlled and monitored for greater reliability. As the internal thread is used to install the Trisert-3®, with engagement in the installation tooling, all internal threads of each insert are automatically checked for the existence of a good thread.

Trisert-3® – Features

Trisert-3® has patented three cutting features to provide more balanced cutting forces and therefore reduced installation torque, compared to the many cross-slot designs available, that only have two cutting features (slots or pierce holes).
