No. 12 Size X 1 In. L Hex Drive Hex Washer Head Self Tapping Roofing Screws

Teks Roofing Screws are self-drilling fasteners designed for secure, weatherproof attachment of roofing and wall panels to steel and wood framing. The integrated drill point eliminates the need for pre-drilling, allowing you to drill, tap, and fasten in a single motion. Each screw features a self-sealing neoprene washer that creates a waterproof seal around the fastener, preventing water infiltration and corrosion at the joint—critical for longevity in harsh outdoor environments.

These screws are ideal for metal roofing installations, HVAC work, steel stud framing, gutter attachment, and pole barn construction. Whether fastening metal-to-metal (26–22 gauge) or metal-to-wood applications, including roofing panels over insulation, Teks Roofing Screws deliver exceptional corrosion resistance without streaking or rust bloom.
