12g X 40mm T17 Hex Flange Roofing Screw Zinc Yellow External Hex 1000 Pack

These 12 gauge (approximately 5.5mm) roofing screws are designed for fixing metal roofing sheets securely. Each screw is 40mm in length, offering good penetration for a strong hold. The T17 slash point makes for fast and easy self-drilling, reducing the need for pre-drilling and saving you time on the job. The Hex Flange Head provides a large bearing surface, distributing pressure evenly to prevent dimpling of the metal sheet and ensuring a weatherproof seal. They're driven with a standard 5/16" nutsetter, a common size found on most Aussie job sites.

Manufactured from hardened steel, these screws offer superior strength and durability. The Zinc Yellow Passivate finish provides good corrosion resistance, protecting against rust and ensuring a long service life, even in harsh Australian conditions. This pack includes 1000 screws, making it ideal for larger roofing projects or keeping your workshop stocked up. These screws are not painted, ensuring a consistent and reliable performance.
