Self-Drilling Screws

Self-Drilling screws also known as Tek-Screws.

Self-drilling screws come in a variety of formats but all are based upon the principle of drilling their own pilot hole and should not be confused with self tapping screws, which need a pre-drilled pilot hole.

They are generally used in steel, softer metals, plastics and there is a range specially designed for use in wood/composite materials.
