Zinc-Plated Roofing Screw

A hex-head roofing screw with a self-drilling point and bonded sealing washer, for fixing metal roofing sheets and cladding to light-gauge steel.

• Zinc-plated hex head with self-drilling point, so no pilot hole is needed in thin steel
• Bonded sealing washer forms a weather-resistant seal when compressed evenly
• Sold in packs of 100, in 4.8 × 19 mm, 5.5 × 32 mm and 5.5 × 38 mm
• Drive the screw square to the sheet and stop as soon as the washer is seated, as overtightening can split or distort the seal
