Product Information
Full details
The Pro-Bolt Dome Head Alloy Bolts are designed for individuals seeking lightweight, corrosion-resistant fasteners for non-safety critical applications, particularly on bodywork and plastics. Their key benefit is a significant weight reduction compared to traditional steel or even titanium bolts, offering an aesthetic and functional upgrade. A key consideration is their lower torque limit, requiring careful application to prevent damage. These bolts are crafted from 7075T73 aluminum, are color anodized for a distinct finish, and are sold in packs of five.

FAQs
What material are these bolts made from?
These bolts are made from 7075T73 aluminum alloy.
How much lighter are these bolts compared to stainless steel?
They are approximately 60% lighter than stainless steel bolts.
Can I use these bolts for critical structural components?
No, these bolts are specifically designed for non-safety critical areas and are not suitable for stress-bearing applications.
What is the recommended torque for these bolts?
Torque recommendations vary by thread diameter. For example, an M5 bolt has a max torque of 2.50 NM (1.84 ft/lbs), and an M6 bolt has a max torque of 5.00 NM (3.69 ft/lbs). Always refer to the provided torque guide.
Are these bolts resistant to rust?
Yes, the anodized finish provides good resistance to corrosion from saltwater, road film, and mild acids.
How should I clean these alloy bolts?
Clean them with a mild soap and water solution using a soft cloth. Avoid abrasive cleaners.
What does 'anodised' mean for these bolts?
Anodising is a process that chemically brightens and applies a colored coating (8-12 microns thick) to the aluminum, enhancing its appearance and corrosion resistance.
Are these bolts sold individually?
No, these bolts are supplied in packs of five.
Troubleshooting
Bolt threads stripping during installation.
You may be overtightening the bolt. Ensure you are using the correct, lower torque settings as specified for alloy bolts. Back the bolt out and re-insert, tightening gently to feel the threads engage properly before applying torque.
Bolt head feels soft or deforms easily.
This indicates you are exceeding the recommended torque limit. Stop tightening immediately. Alloy bolts are lighter and softer than steel and require careful torque management.
Color appears faded after a short period.
While anodizing offers good color retention, prolonged exposure to direct sunlight or harsh chemicals can cause fading. Ensure the bolts are not exposed to excessive UV or chemical agents. Clean gently with mild soap and water.
Bolt does not fit the existing hole.
Verify that you have selected the correct thread diameter (e.g., M5, M6) and pitch (e.g., 0.80mm, 1.00mm). Refer to the product's specific dimensions or consult your vehicle/equipment manual.
Pros and Cons
Pros
- Significantly lighter than steel and titanium fasteners.
- Excellent resistance to corrosion from environmental factors.
- Provides a clean, aesthetic finish for visible components.
- Durable, chemically brightened, and color-anodized surface.
- Ideal for upgrading the look and reducing weight on bodywork and plastics.
Cons
- Not suitable for safety-critical or stress-bearing applications.
- Requires lower torque settings than original bolts to prevent damage.
- Aluminum is a softer material and can be more prone to stripping if over-tightened.
- Color may fade over extended periods of extreme UV exposure.
Setup, Compatibility & Care
Setup: Ensure you select the correct thread diameter, pitch, and length for your application. Measure your original bolts carefully. Always refer to the torque guide provided to avoid damaging the fastener or the component it's securing. Hand-tighten initially to ensure the threads are engaged correctly.
Compatibility: These bolts are suitable for non-safety critical applications only. They are ideal for use on mudguards, screens, fairings, engine casings, huggers, fuel caps, number plates, lamp units, exhaust cans, heel plates, clutch levers, exhaust manifold brackets, fuel cap surrounds, air filters, and car rocker covers. Do not use in any stress area applications.
Care: Clean the bolts with a mild soap and water solution using a soft cloth. Avoid using abrasive cleaners or solvents, as these can damage the anodized finish. Periodically check that bolts remain securely fastened, especially after initial installation, and re-torque if necessary according to the recommended values.
