Washer roofing screws with EVA sealing washers provide superior weatherproofing for metal roofing applications. The 20mm washer diameter creates a tight seal that prevents water ingress and extends roof lifespan in harsh South African conditions. Each pack contains 100 screws, ideal for both new installations and repairs. The EVA washer material resists UV degradation and temperature fluctuations, maintaining its seal integrity over years of exposure. Perfect for securing corrugated iron sheets, metal cladding, and roofing panels to timber or steel substrates. Corrosion-resistant coating ensures long-term durability in coastal and high-rainfall areas. Essential hardware for professional roofers and DIY projects requiring reliable fastening solutions.
