What is the Difference Between a Self-Drilling Screw and a Self-Tapping Screw?

26 Mar.,2024

 

Self-Tapping Screws are one of the most commonly used industrial fasteners. As on of the earliest engineered fastener products, self-tapping screws were manufactured out of hardened steel, and their use powered the Industrial Revolution. Still incredibly common today, self-tapping screws now include many styles and types made for specific fastening functions.

Terminology used in the commercial fastener trade, unlike that used in aerospace or military fasteners, can be imprecise and often cause confusion. A prime example of this impreciseness is the distinction between self-tapping screws and self-drilling screws.
