Teks 21418 Roofing Screws, Hex Washer Head, Zinc-plated, #12 X 1 In., 300-pk.

Teks 21418 roofing screws are engineered for fast, secure fastening of corrugated metal panels to steel framing and treated lumber without pre-drilling. Each screw features a hex washer head with an integrated self-sealing neoprene washer that creates a waterproof seal, preventing water infiltration at fastening points—a critical requirement in roofing and exterior applications where moisture damage can lead to costly repairs.

The zinc-plated steel construction with premium coating resists corrosion and rust in harsh outdoor environments, making them ideal for metal roofing, HVAC installations, steel stud framing, gutters, and register vents. This 300-pack provides ample fasteners for both commercial and residential roofing projects.
