Product Information
Full details
These Pro-Bolt Dome Head Alloy Bolts are designed for enthusiasts seeking lightweight replacements for non-safety critical components on their vehicles. Offering a significant weight reduction compared to steel and titanium fasteners, they provide a durable and aesthetically pleasing upgrade. However, their softer material composition means they are unsuitable for stress-bearing applications and require careful torque application to prevent damage.

FAQs
What material are these bolts made from?
These bolts are made from 7075T73 alloy, a lightweight and strong aluminum alloy.
Are these bolts suitable for engine mounting?
No, these bolts are specifically recommended for non-safety critical areas and are not suitable for any stress area applications, including engine mounting.
How do I know which size bolt I need?
You need to measure the diameter and length of the bolt you are replacing, and identify the thread pitch (e.g., M5 x 0.80mm). Check the original bolt or your vehicle's manual for specifications.
Can I use these bolts on my motorcycle's exhaust?
Yes, they can be used on exhaust cans where heat is not excessive and the bolts are not load-bearing. Avoid using them on exhaust manifold brackets that experience high heat and stress.
How should I clean the anodised finish?
Clean gently with a damp cloth and mild soap. Avoid abrasive cleaners, solvents, or power washers, which can damage the anodised coating.
What does 'anodised' mean for these bolts?
Anodising is a process that hardens the surface and provides a durable, coloured finish resistant to corrosion. The thickness for these bolts is between 8 and 12 microns.
How much lighter are these bolts compared to steel?
These alloy bolts are approximately 60% lighter than stainless steel bolts.
Troubleshooting
Bolt head stripping during tightening
You are likely exceeding the recommended torque. Use a torque wrench and consult the torque guide provided. Ensure the tool is properly seated on the bolt head.
Bolt not seating correctly
Verify that you have selected the correct thread diameter and pitch for your application. Ensure the threads in the receiving component are clean and undamaged.
Discoloration or fading of the anodised finish
Avoid exposing the bolts to harsh chemicals or prolonged UV radiation. Clean gently with mild soap and water. Some natural aging may occur over time.
Bolt feels too soft or deforms easily
This indicates the bolt is being used in an application that requires a stronger material. Replace with a bolt designed for stress-critical areas. Do not overtighten.
Pros and Cons
Pros
- Significantly lighter than traditional steel or titanium bolts.
- Excellent resistance to corrosion from common environmental factors.
- Enhances the visual appeal with a clean dome head and coloured finish.
- Wide range of sizes and colors to match specific applications and aesthetics.
- Durable anodised finish resists fading and damage.
Cons
- Not suitable for safety-critical or high-stress applications.
- Softer material requires careful torque management to avoid stripping or damage.
- Can be more susceptible to scratching than harder materials.
- Specific torque values must be adhered to, which may differ from original bolts.
- Sold in packs of 5, which may not be ideal for all projects requiring a different quantity.
Setup, Compatibility & Care Instructions
Setup: These bolts are designed as direct replacements for existing fasteners. Ensure you select the correct thread diameter, pitch, and length for your application. When tightening, always refer to the recommended torque values to prevent damage to the bolt or the mating component.
Torque Guide:
| Thread Diameter | Max Torque (NM) | Max Torque (ft/lbs) |
| --------------- | --------------- | ------------------- |
| M4 | 1.20 | 0.88 |
| M5 | 2.50 | 1.84 |
| M6 | 5.00 | 3.69 |
| M8 | 10.00 | 7.38 |
Compatibility: Suitable for use in all non-safety critical areas such as mudguards, screens, fairings, engine casings, huggers, fuel caps, number plates, lamp units, exhaust cans, and more. *Not* suitable for any stress area applications.
Care: Clean with a damp cloth and mild soap if necessary. Avoid abrasive cleaners or solvents that could damage the anodised finish. Ensure threads are clean before installation and consider using a suitable anti-seize compound for certain applications, checking compatibility with the alloy.
