Trilobular® Thread-Rolling Screws

The Trilobular® thread profile of these screws improve thread-forming and thread engagement within softer materials by improving displacement of material into relief areas when driven into the substrate. This increases the resistance to vibrational loosening forces. The higher quality internal threads produced by these Trilobular® thread-rolling screws also reduces material failure and improves holding power. It also reduces stripping, pull-out and allows for repeated removal and insertion into the same tapped hole.

Many Styles and Materials

Trilobular® thread-rolling screws are available in steel with the following head styles: flat head and hex indented washer head, drives: Phillips drive and with either a clear zinc or black oxide finish.
