12g X 25mm T17 Hex Flange Roofing Screw Galvanised C4 External Hex 500 Pack

Solid Roofing Screws, Sorted.

Need a reliable roofing screw that can handle the Aussie climate? These 12g x 25mm galvanised screws are built tough for securing roofing sheets to timber or steel battens.

This pack of 500, 12 gauge by 25mm roofing screws from Hardware Depot are built to get the job done. They're made from hardened steel to withstand the rigours of installation and resist bending or snapping. The Type 17 slash point ensures quick and clean penetration through roofing materials, reducing the risk of splitting the timber.

Each screw features a 5/16" external hex flange head, designed for easy driving with a nutsetter. The flange head provides a larger bearing surface, offering increased holding power and preventing pull-through. Finished with a Galvanised Class 4 coating, these screws provide excellent corrosion resistance against the elements, making them suitable for external applications. With 11 threads per inch these screws will securely bite in and stay secure in your timber.

These screws are the right size for most corrugated and metal roofing projects. Each screw has a 12g gauge, about 5.5mm, so they are the right size to get into the material without splitting it.

Pro Tip: When installing roofing screws, use a variable speed drill with a nutsetter attachment. Start slow to allow the screw to bite and then increase the speed to drive it in smoothly. Avoid over-tightening, which can strip the threads or damage the roofing material. Pre-drilling might be necessary when working with hardwood battens.
