About Tapping Screws

Compare drilling, pointed, thread-forming, and thread-cutting tips to find the best choice for your material.

Stainless Steel Phillips Rounded Head Screws for Sheet Metal

Our most popular sheet metal screws also resist rust. Their pointed tip starts a hole in sheets up to 0.025" thick, but for thicker material you’ll need to drill first. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.

Length is measured from under the head.

18-8 Stainless Steel—The choice for wet and outdoor environments. However, these screws won't hold up to the harsh chemicals that 316 stainless steel can.
