ForgeFix Roofing Bolts M6 x 16mm Zinc Plated Bag 25

Forgefix Roofing Bolt ZP M6 x 16MM is a double slotted bolt complete with a square nut and a low profile mushroom head. The bright zinc-plated finish provides corrosion resistance, making these bolts suitable for both interior and exterior use, even in exposed weather conditions. Each pack includes 25 bolts with square nuts designed for secure fastening in roofing and other joining applications. The bolts are fully threaded and come with the appropriate square nuts to ensure firm assembly. The recommended clearance hole size is typically 1 mm larger than the bolt diameter to accommodate proper fitment. Zinc coatings form a protective barrier and can act as a sacrificial anode if damaged, helping to extend the finish’s life. The zinc oxide layer acts as a barrier to further oxidation, similar in concept to oxide layers found on aluminium and stainless steels. When installing, choose a screwdriver tip that matches the slot width to prevent head damage, with flared tips suitable for most uses and parallel tips for driving the bolt below the material surface.
