SCREW THREAD INSERTS

Designed for applications where friction-reducing coatings and platings are prohibited for fear of contamination, Heli-Coil's Heli-Tronic™ Inserts help to prevent seizing of fasteners in threaded assemblies.

The inserts reduce friction force an average of 35 percent when compared with standard tapped threads.

Manufactured from a specially-developed 18-8 stainless steel and work-hardened to Rockwell C 43-50, these inserts also provide superior corrosion resistance with virtually no thread wear and magnetic permeability. Tapped threads are greatly strengthened due to the inherent flexibility of the insert providing a more balanced load distribution.
