The Unifix Hook Bolts and Nuts (M8 x 180, Gold, ZYP coating) are designed for professionals and DIY enthusiasts needing secure and durable roofing fixings. Their primary benefit is providing a strong, corrosion-resistant hold for various construction applications. A potential caveat is the specific M8 x 180 size, which may not suit all project requirements. This product offers high-quality steel construction with a protective ZYP coating for longevity, quick installation via its hook design and included nuts, and is supplied in a box of 100 sets for convenience on larger jobs.

The Unifix hook bolts and nuts are made from durable steel.
The ZYP coating provides enhanced corrosion resistance, protecting the steel from rust and wear.
Each box contains 100 sets of M8 x 180 hook bolts and nuts.
Yes, each set includes one hook bolt and one matching nut.
They are primarily engineered for secure roofing fixings and general standard construction applications.
The size is M8 for the diameter and 180mm for the length.
While they offer reliable strength for standard applications, always ensure the load capacity of the bolt and the surrounding materials meet project specifications for heavy-duty use.
Ensure the hole is the correct size for an M8 bolt and is free from obstructions. Check that the nut is aligned correctly before tightening.
Verify that the bolt and nut are the same thread size (M8). Clear any debris from the bolt threads and the nut's internal threads. Ensure materials are properly aligned and not creating shear stress.
While ZYP offers good protection, extreme or prolonged exposure to harsh chemicals or environments can still cause minor surface rust. Clean the affected area and ensure the fastener is still structurally sound. For critical applications, consider replacing if significant degradation occurs.
Setup: To install, align the hook end of the bolt with the pre-drilled hole or desired fixing point. Pass the bolt through the material being attached. From the opposite side, place the included nut onto the threaded end of the bolt and tighten securely using an appropriate wrench or socket set. Ensure the nut is fully engaged and the attached materials are firmly held.
Compatibility: These M8 x 180 hook bolts are designed for use with standard M8 nuts and washers. They are compatible with materials commonly found in roofing and construction, such as timber beams, steel purlins, and sheeting. Ensure the substrate can support the bolt and the load it will carry.
Care: While the ZYP coating provides excellent corrosion resistance, it is recommended to keep the bolts clean and free from excessive dirt or debris. Periodically inspect fixings in critical applications for any signs of damage or wear. Avoid using abrasive cleaners that could damage the coating. Store unused bolts in a dry environment to maintain their condition.
