Description

A Self-drilling screw is, essentially a self-tapping screw with the added feature of a drill point end. Self-drilling screws eliminate the need for a pre-drilled pilot hole as they perform the drilling, tapping, and fastening in one action. Hardened steel fixings are generally used when fixing metal to metal or metal to timber.
