ForgeFix Roofing Bolts M6 x 40mm Zinc Plated Bag 25

These Forgefix double slotted roofing bolts are designed for exceptional durability and versatility. Each bolt is supplied with a square nut and features a low profile, cross slotted mushroom head, making them suitable for a variety of applications beyond just roofing.

Corrosion Resistance

One of the standout features of these roofing bolts is their bright zinc plated finish, which enhances resistance to corrosion. This makes them ideal for both interior and exterior use, as they can withstand different weather conditions without the risk of rusting. The zinc coating acts as a protective barrier for the metal beneath, helping to prolong the lifespan of the bolts. In the instance that this barrier becomes damaged, the zinc serves as a sacrificial anode, protecting the underlying metal from oxidation.

Application Versatility

While these roofing bolts are commonly associated with roofing applications, they are versatile and can be used for a variety of purposes where products need to be securely joined together. This flexible use makes them an excellent addition to any toolbox or project kit.

For optimal performance, it is recommended to use clearance drill sizes that are 1mm larger than the bolt diameter. This ensures a proper fit and facilitates easier assembly.

Technical Specifications

- Double slotted design allows for use with slotted screwdrivers, which are essential for secure installation. It is crucial to use a screwdriver whose tip matches the width of the screw slot to prevent damage to the screw head. Slotted screwdrivers are available in two types: flared and parallel. The flared tip is ideal for most applications, while the parallel tip is better suited for instances where the bolt needs to be driven below the material surface.

- Each bolt is fully threaded, providing greater grip and holding power.

- The bolts weigh 0.68 pounds, making them robust enough for structural applications yet manageable for handling without excessive strain.

The zinc coating also helps prevent oxidation of the protected metal, contributing to a longer-lasting finish. When it oxidizes, zinc forms a fine white dust, zinc oxide, which, unlike iron oxide, does not compromise the integrity of the substrate’s surface. If intact, this zinc oxide layer can continue to protect against further oxidation, similar to the protective oxide layers found on aluminium and stainless steel.

In summary, the Forgefix double slotted roofing bolts, complete with square nuts and low profile mushroom heads, are a highly reliable choice for both residential and commercial projects. Their corrosion-resistant properties, combined with their versatility, make them suitable for a wide range of applications beyond roofing, ensuring they meet the needs of various users.
