About This

【 Durable Construction 】 - High-strength 1022A carbon steel screws paired with corrosion-resistant rubber washers (EPDM) ensure long-lasting performance, resistant to rust and weathering.
【 Anti Corrosion Coating 】 - These sheet metal screws are coated with weather resistant layer, the surface has passed 1000 hours of salt spray testing, which makes the roofing screws more waterproof, rust proof, and corrosion-resistant, They can endure and resist the rusting effect of sun and rain.
【 Self-Drilling Efficiency 】 - Sharp self-drilling tips eliminate pre-drilling needs, while coarse threads provide superior grip in wood, plastic, and thin metal sheets under 2.4mm thickness.
【 Weatherproof Seal 】 - 13.8mm (1/2") compressible washers create a watertight barrier by expanding under pressure, effectively covering screw holes to prevent leaks.
【 Applications 】 - Ideal for securing metal panels, composite boards, plastic sheets, and wood in roofing, construction, manufacturing, and DIY projects. Hex head design allows high-torque driving.
