The Unifix Hook Bolts and Nuts (M8 x 100) are essential hardware components designed for professional contractors and DIY enthusiasts working on roofing and structural construction projects. These fasteners provide a secure, high-strength connection for anchoring materials, offering excellent durability thanks to their gold corrosion-resistant coating. While they offer superior stability in outdoor environments, users should ensure the M8 size is compatible with their specific pre-drilled holes or bracket thickness before purchasing.

Yes, they feature a corrosion-resistant gold coating specifically designed to withstand harsh weather and outdoor exposure.
Yes, each bolt is supplied with the corresponding nut for a complete fastening solution.
These bolts measure 100mm in length.
While they are strong, they are primarily designed for roofing and general construction fastening; consult a structural engineer for load-critical steel joints.
They are made from high-strength steel with a protective gold-colored anti-corrosion finish.
Ensure the pilot hole is at least 8.5mm to 9mm in diameter to accommodate the M8 bolt shaft.
Check the threads for construction debris or metal burrs; clean with a wire brush if necessary.
Verify that the nut is fully tightened and use a washer if the surface material is softer than the metal bolt.
Installation of the Unifix Hook Bolts is straightforward. Start by marking your drilling points precisely to ensure the hook aligns correctly with the support structure. Use an M8-compatible drill bit to create the pilot hole, then insert the bolt, ensuring the hook is seated firmly. Tighten the provided nut securely, but avoid excessive torque that could deform the roofing surface.
Compatibility: These are M8 bolts, meaning they are best suited for pre-drilled holes slightly larger than 8mm to allow for thermal expansion.
Care: While the gold coating is corrosion-resistant, avoid using high-impact power tools that may strip the threading or damage the protective finish. If the bolts are exposed to severe salt spray, periodic inspection for signs of debris buildup is recommended.
