Washer roofing screws with EVA washers are essential fasteners for securing metal roofing sheets, cladding, and corrugated panels. The 20mm washer diameter provides excellent load distribution and weather resistance, preventing water infiltration around screw penetrations. These screws feature a resilient ethylene-vinyl acetate (EVA) washer that compresses under load to create a watertight seal, making them ideal for outdoor applications exposed to rain, wind, and temperature fluctuations.
Commonly used in roofing installations, agricultural buildings, industrial structures, and carport construction, washer roofing screws accommodate substrate movement without compromising the seal. The EVA washer material remains flexible across temperature ranges, reducing the risk of cracking or hardening over time. This pack of 100 screws provides sufficient fasteners for medium-sized roofing projects. Suitable for use with metal sheeting, polycarbonate panels, and composite materials. Corrosion-resistant coating ensures durability in harsh environmental conditions.
