8 x 1/2 in. Self-Drilling Metal Screws, Zinc, Hex Head

Self-Drilling Metal Screws, Zinc, Hex-Drive

These #8 x 1/2 in. self-drilling metal screws make fastening sheet metal quick and convenient. Also known as Tek screws, they feature a hardened self-drilling point that drills through metal and creates its own threads as the screw is driven. This eliminates the need to pre-drill a separate pilot hole in many applications, helping you save time during installation.

The 1/4 in. hex-drive head provides a secure connection for a nut driver or hex driver, making these screws easy to install with a drill or power driver. The zinc-plated finish provides a clean appearance and helps protect the steel from corrosion in typical indoor and general-purpose applications.

Self-Drilling Design

The specialized drill point is designed to penetrate sheet metal efficiently, while the hardened threads tap the material as the screw advances. This combination allows the screw to drill, tap, and fasten in one operation, making it particularly useful for metal fabrication, HVAC work, ductwork, light-gauge steel, and general assembly projects.
