Product Information
Full details
The Unifix M8 x 160 Hook Bolts and Nuts are designed for professional contractors and DIY enthusiasts requiring reliable, heavy-duty fastening solutions for roofing and construction projects. These fasteners offer exceptional holding strength and enhanced corrosion resistance thanks to their Zinc Yellow Passivate (ZYP) finish, making them ideal for long-term outdoor exposure. While they provide excellent structural integrity, users should ensure they are using the correct drilling size to prevent damage to the substrate during installation.

Extended Product Information
FAQs
Are these bolts suitable for marine environments?
While the ZYP coating offers good corrosion resistance, they are not specifically rated for constant exposure to salt spray; stainless steel alternatives are recommended for marine use.
Can I use these for timber framing?
Yes, these are excellent for heavy-duty timber applications where structural security is required.
Does the package include washers?
The product includes the bolt and the nut; check your specific hardware requirements as additional flat or spring washers may be needed depending on your project.
What is the benefit of the ZYP coating?
Zinc Yellow Passivate provides a thicker, more durable sacrificial layer against rust compared to standard bright zinc plating.
Can I paint over these bolts?
Yes, once installed, you can use a metal-compatible primer and paint, though it is not necessary for the performance of the bolt.
Troubleshooting
Bolt is difficult to insert through the material
Check if the pilot hole is misaligned or too small; re-drill using a drill bit one size larger.
Nut feels loose or backs off over time
Ensure the washer (if applicable) is seated correctly and consider using a thread-locking compound if subjected to heavy vibrations.
Surface rust appears on the bolt head
This may indicate the ZYP coating was compromised during installation. Clean the area and apply a cold-galvanizing spray to restore protection.
Pros and Cons
Pros
- Superior corrosion resistance due to ZYP coating
- High structural integrity for heavy-duty applications
- Comprehensive kit includes both bolts and nuts
- Standardized threading for easy tool usage
Cons
- Requires precise pilot hole drilling to avoid material splitting
- Gold finish may be aesthetically incompatible with silver-toned hardware
- Not intended for marine environments with high salt exposure
Setup, Compatibility & Care
Installation requires standard metric hand tools or an impact driver with the appropriate socket size.
- Preparation: Measure the thickness of the materials being joined to ensure the 160mm bolt length provides sufficient protrusion.
- Drilling: Use a drill bit slightly larger than the M8 shaft diameter to ensure a smooth passage while maintaining enough friction for a secure fit.
- Tightening: Thread the nut onto the bolt by hand initially to prevent cross-threading, then tighten with a wrench.
Care: While the ZYP coating is resistant to rust, avoid using abrasive cleaners or power tools that may strip the protective finish. Periodically inspect fasteners in high-vibration areas to ensure nuts remain tight.
