Our #7 diameter 9/16" self-piercing screw is an ideal choice for fastening sheet metal or assembling metal frames without needing pilot holes. The pointed end can penetrate through hard and soft materials, and the fully threaded twin leads keep the screw secure long after being driven.

This screw features a slotted head with an indented hex washer that spreads the weight and load over a greater area. The carbon steel composition and corrosion-resistant zinc plating results in a strong screw and shiny appearance. We also have painted self-piercing industrial screws with color matching available upon request.
