Galvanised Bitumen Roofing Drive Nails 2.8mm x 70mm

These galvanised drive nails are intended for securing corrugated bitumen roofing sheets and creating a sealed fixing point through the roof covering. Each fixing includes a 2.8mm x 70mm galvanised countersunk nail and a PE sealing washer. The washer helps resist water ingress around the fixing, while the metal nail provides the mechanical connection to the roof support. The nail and washer arrangement is suited to the raised crowns of corrugated bitumen sheets, keeping the fastening detail consistent across the roof. They are a purpose-made fixing component for this style of roofing.
