ForgeFix M6 x 70mm Zinc Plated Roofing Bolts (Pack of 25)

ForgeFix M6 x 70mm Zinc Plated Roofing Bolts offer a durable and corrosion-resistant fastening solution, featuring a low-profile mushroom head with double slots for secure tightening. These bolts come with square nuts and are finished with a bright zinc plating that enhances their resistance to rust and corrosion, making them suitable for both interior and exterior applications, including those exposed to harsh weather conditions.

The zinc plating acts as both a protective barrier and a sacrificial anode, ensuring long-lasting performance by preventing oxidation. The formation of zinc oxide, a fine white dust, further protects the bolt without compromising the substrate’s integrity, similar to the protective oxide layers found on aluminium and stainless steel.

Key Features:

• Material: Zinc-plated steel
• Head Type: Low-profile mushroom head with double slots
• Included: Square nuts
• Corrosion Resistance: Bright zinc plating for enhanced durability
• Drill Size Recommendation: 1mm larger than bolt diameter (7mm for M6 bolts)
• Versatile Use: Suitable for roofing and general fastening applications

Application Tips:

• Use a slotted screwdriver with a tip width that matches the screw slot to avoid damaging the bolt head.
• For recessed installations, opt for a parallel-tip screwdriver instead of the more common flared-tip design.
• Ideal for joining materials where low-profile fastening is required.

ForgeFix roofing bolts are a reliable choice for professionals and DIY enthusiasts seeking robust, weather-resistant fasteners.
