About Tapping Screws

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

Stainless Steel Phillips Oval Head Screws for Sheet Metal

These corrosion-resistant screws have a decorative rounded top that peeks out from the surface of trim work. Beveled under the head, they’re often used in countersunk holes. Their pointed tip starts a hole in sheet metal 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.

Length is measured from the edge of the head.

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