ForgeFix Roofing Bolts M8 x 160mm Zinc Plated Bag 10

The Forgefix Double Slotted Roofing Bolt is an essential component for a variety of applications beyond just roofing. Designed with functionality and resilience in mind, this bolt features a unique low-profile cross slotted mushroom head and is supplied with a square nut for secure fastening.

Material and Finish

Constructed from durable materials, the bolts are finished with a bright zinc plating that provides enhanced corrosion resistance. This makes them suitable for both interior and exterior use, allowing them to be exposed to various weather conditions without the risk of rusting. The zinc coating not only prevents oxidation but also creates a barrier that contributes to a longer lasting finish. In the event that this barrier is compromised, the zinc acts as a sacrificial anode, protecting the underlying metal. Unlike iron oxide, which can lead to significant surface damage, the formation of zinc oxide creates a fine white dust that helps maintain the integrity of the substrate. Moreover, if left undisturbed, zinc oxide can further protect against oxidation, much like the natural oxide layers found on aluminium and stainless steel.

Specifications

- Fully threaded design for optimal gripping power

- Clearance hole size should be 1mm larger than the bolt diameter to facilitate easy installation

- Ideal dimensions of the bolt are M8 x 160mm, making it a versatile choice for various fastening needs

Usage Guidelines

When using these bolts, it is important to select the appropriate slotted screwdriver. Ensuring that the screwdriver tip matches the width of the screw slot is crucial, as mismatched tools can damage the screw head. Slotted screwdrivers come in two main types: Flared and Parallel. For most applications, a Flared tip is recommended due to its compatibility with standard fastening tasks. However, if the screw or bolt needs to be driven below the surface of the material, a Parallel tip screwdriver should be used to achieve the desired depth without compromising the screw's integrity.

In summary, the Forgefix Double Slotted Roofing Bolt offers a robust, reliable fastening solution designed for diverse applications. With its thoughtful design features and durable finish, it stands out as an essential choice for both professional tradespeople and DIY enthusiasts alike. Whether you are working on roofing projects or joining other materials together, these bolts provide the strength and reliability needed to ensure long-lasting connections.
