ForgeFix ZP M8 x 200mm Roofing Bolts, Bag of 10

The ForgeFix ZP M8 x 200mm Roofing Bolts are designed for durability and versatility, featuring a bright zinc-plated finish that significantly enhances their resistance to corrosion. These bolts are suitable for both interior and exterior use, making them ideal for environments exposed to harsh weather conditions without the risk of rusting.

These double-slotted roofing bolts come with square nuts and a low-profile mushroom head, providing a secure and neat finish. The zinc plating not only forms a protective barrier against oxidation but also acts as a sacrificial anode if the coating is compromised, ensuring long-lasting performance.

Usage Advice

For optimal results, use a clearance drill size 1mm larger than the bolt diameter. When working with slotted screwdrivers, ensure the tip matches the width of the screw slot to avoid damaging the bolt head. Flared tip screwdrivers are recommended for most applications, while parallel tips are better suited for driving screws below the material surface.

Common Applications

• Roofing projects
• Joining materials in construction
• General DIY and carpentry
• Outdoor fixtures requiring weather-resistant fasteners

Why Zinc Plating?

Zinc coatings prevent oxidation by forming a protective barrier. Unlike iron oxide, zinc oxide does not compromise the substrate's integrity, acting as a durable shield similar to the oxide layers on aluminium and stainless steel.
