Galvanised Extra Large Head Clout Nails are designed for maximum holding power where thin sheet materials risk pull-through. The oversized, low-profile head spreads load over a wider area, making them ideal for fixing roofing felt, shingles, membranes, insulation facings, thin plywood, and other sheet products. Manufactured from robust carbon steel and hot-dip galvanised for long-lasting corrosion resistance, these nails deliver secure, reliable fixings for both indoor and outdoor applications. Supplied in trade-friendly 1kg bags across popular lengths.
