Galvanised Clout Nail 40mm (3kg/Tub)

40mm Galvanised Clout Nails for medium to heavy-duty exterior fixings in roofing, insulation, and sheeting. Each nail is manufactured from carbon steel with a hot-dip galvanised coating, offering long-term corrosion resistance for exterior use. The large flat head spreads load to prevent tearing or pull-through on softer materials, while the sharp point allows smooth penetration and firm hold in timber. The 40mm length provides deeper penetration for thick or dense materials, while the broad flat head delivers secure coverage and reduces the risk of surface tearing. 3kg tub format offers ample quantity for ongoing trade or site use.
