Self-drilling 5/16" hex head screws designed for fastening metal-to-metal connections in HVAC, electrical, and construction installations. These screws feature a hardened drill point that eliminates the need for pre-drilling, allowing fast and efficient installation through sheet metal and light structural steel. The hex washer head provides strong clamping force and secure fastening while the zinc-plated finish helps resist corrosion in indoor and light industrial environments.
Commonly used for ductwork installation, metal framing, brackets, and mechanical support systems.
