Galvanised nail roof and barrel washer combination designed for secure fastening of roofing materials and sheet metal applications. The 6.3mm diameter shaft with 120mm length provides optimal penetration and holding power, while the integrated barrel washer distributes load across a wider surface area to prevent material pull-through. Ideal for corrugated iron, asbestos cement sheets, and metal cladding installations. Corrosion-resistant finish ensures long-term durability in outdoor environments. Supplied in quantities of 50 per box for professional contractors and builders.
