Roofing Bolt 25RBN830 M8 x 30mm Zinc-Plated Bag 25

These Forgefix double slotted roofing bolts are designed for durability and corrosion resistance. They feature a low-profile mushroom head and are supplied with square nuts for secure fastening. While primarily used in roofing applications, they are versatile enough to join various materials and are suitable for both interior and exterior use, including weather-exposed environments. The bolts have a bright zinc plated finish that helps prevent oxidation by forming a protective barrier and can act as a sacrificial anode if the coating is damaged, contributing to a longer-lasting finish. Zinc coatings reduce metal oxidation and, when intact, zinc oxide forms a barrier that limits further corrosion. When using slotted screwdrivers, selecting a tip that matches the screw slot width is important to avoid damaging the screw head. The product is compatible with standard slotted drivers and is supplied in a bag with square nuts for ready installation.
