ForgeFix Roofing Bolts M6 x 70mm Zinc Plated Bag 25

These Forgefix double slotted roofing bolts are designed for secure fastening in roofing and other joining applications. Supplied with square nuts, they feature a low-profile mushroom head and a bright zinc plated finish that enhances corrosion resistance. Suitable for interior and exterior use, these bolts can withstand weather conditions without rusting, thanks to the protective zinc coating which helps prevent oxidation by forming a barrier and, if damaged, acting as a sacrificial anode. The design includes a fully threaded shaft and a cross-slotted head, and a clearance hole size typically 1 mm larger than the bolt diameter for proper fit. These characteristics make them a practical choice for durable, long-lasting joins beyond roofing too.
