14g X 65mm T17 Cyclone Hex Flanged with Aluminum Seal Roofing Screw + Multi Seal + Shankguard Galvanised C4 External Hex Drive 250 Pack

These 14g x 65mm roofing screws are designed for serious holding power. The T17 slash point ensures fast and easy penetration through roofing materials, minimising surface damage and reducing the risk of 'walking'. We've included the Cyclone Hex Flanged head with an aluminum seal which, combined with the Multi Seal, forms a robust and reliable barrier against water ingress. The Shankguard protects the screw shank during installation, preventing premature failure. Manufactured from hardened steel and finished with a Galvanised Class 4 coating, these screws offer superior corrosion resistance, making them ideal for external applications and coastal environments. The 3/8" Hex Socket drive makes installation quick and easy with standard nut setters. Supplied in a convenient 250 pack, you'll have plenty to get the job done.
