Products / Self-Drilling Screws

Self-Drilling Screws
Drill, tap and fasten — in one drive.

Tek-type self-drilling screws eliminate the pilot hole. The hardened drill point bores through sheet steel, the cutting flutes evacuate chips, and the formed thread engages — all without the operator changing tools.
