Tri-Lobular Thread Forming Screws for Metal Applications at Empire Bolt & Screw

The ability of Tri-Lobular Thread Forming Screws to create their own threads in metal has revolutionized this fastener application.  No longer are pre-tapped holes required, virtually eliminating one entire step of an installation process on the manufacturing floor.   Trilobular thread shape reduces friction during thread formation and provides exceptional prevailing torque.  Work-hardening occurs on the formed internal threads, introducing a high-strength nut thread that is uniquely resistant to loosening by vibration.
