Self-drilling Screw Introduction

Self drilling screw which means that, in addition to the tap-like flute in the leading threads, there is also a preliminary drill-like fluted tip that looks much like the tip of a center drill. These screws combine a thrilling-like action and the fastener installation itself into only one driving motion (instead of separate drilling, tapping, and installing motions); they are thus very efficient in a variety of hard-substrate applications, from assembly lines to roofing.

Self drilling screws have a drill-bit point to enable drilling into metal without first creating a pilot hole.They are available in all shapes,sizes and numerous different head types.
