Versatile Application: these 10 x 1-1/2" roofing screws securely fasten thin metal sheets (under 2.4mm) to wooden structures, crafted from durable carbon steel for exceptional strength and fracture resistance
Weatherproof and Anti Loose Design: the 1/2" (13.8mm) EPDM washer expands under pressure, creating a tight, weather-resistant seal while preventing loosening over time
Effortless Installation: self drilling tips eliminate bit slippage, and coarse threads optimize grip in wood, compatible with steel, aluminum, plastic, and composite panels
Corrosion Resistant Finish: the signal white baked coating on the 5/16" hex head offers corrosion protection and blends seamlessly with popular roof colors
Important Note: not recommended for metal sheets thicker than 2.4mm or metal to metal connections, ensure proper angling during use to prevent slipping
