14g X 50mm T17 Hex Flange with Seal Roofing Screw + Washer + Shankguard Galvanised C4 External Hex Drive 500 Pack

This pack of 500, 14 gauge by 50mm roofing screws are designed for securing roofing sheets to timber or steel battens. Each screw features a T17 slash point for fast, self-drilling penetration, minimising the need for pre-drilling. The hex flange head with integrated seal provides a broad clamping force and weather-tight seal, preventing leaks and corrosion around the fixing point. These screws also include a Shankguard design which protects the screw shank and provides additional pull-out resistance.

Manufactured from hardened steel, these screws are finished with a Galvanised Class 4 coating for superior corrosion resistance in harsh environments, making them ideal for coastal or industrial applications. The 3/8" hex drive is compatible with standard nutsetters for fast and efficient installation. With 10 threads per inch, these screws provide a strong and secure hold. These screws are a solid choice for any roofing project.
