Self-drilling screws are specialized fasteners designed to penetrate materials without the need for a pre-drilled pilot hole. Commonly referred to as Self-Drilling SMS (Sheet Metal Screws), these screws are widely used for joining sheet metal components with ease and efficiency.
They are available in various head styles and drive types to suit different installation needs. Typically, self-drilling screws are manufactured from zinc-plated steel, with optional black oxide or cadmium coatings, as well as corrosion-resistant stainless steels like 18-8 (AISI 304) and 316 grade for enhanced durability in demanding environments.
