80mm Galvanised Hex Flange Wood Screw with EPDM washer (30 Pack)

This 6.3 × 80mm hex flange head wood screw is designed for strong, reliable fixing in timber applications, making it ideal for solar mounting, roofing, and exterior construction. Manufactured from C1022 carbon steel, the screw provides high strength and durability while driving easily into wood.

The screw is supplied with a 14mm OD vulcanised bonded washer, combining 0.8mm 275g hot-dip galvanised steelwith 2mm black EPDM rubber. This creates a secure compression seal that helps prevent water ingress and protects the fixing point from corrosion, making it well suited to outdoor environments.

The hex flange head allows for strong torque transfer and fast installation using standard hex drivers, while the integrated washer ensures a clean, professional finish and long-lasting weather protection.
