Product Information
Full details
The Pro-Bolt Alloy Nyloc Nuts in blue are designed for enthusiasts looking to reduce weight and add a vibrant aesthetic touch to non-safety critical motorcycle or automotive components. These high-quality aluminium fasteners provide excellent resistance to environmental factors like salt and road film, making them a perfect upgrade for cosmetic bolt-on parts. However, because they are crafted from lightweight alloy, they are strictly not suitable for high-stress or safety-critical applications where steel or titanium hardware is required.

FAQs
Are these nuts safe for engine mounting points?
No. These are for non-safety critical applications only and should not be used on high-stress components like engine mounts or brake systems.
Why is the blue finish so durable?
The nuts undergo a chemical brightening and anodising process that results in a 8-12 micron thick layer, protecting the aluminium from road salt and film.
Can I use these to replace heavy stainless steel nuts?
Yes, provided the application is not safety-critical. They are roughly 60% lighter than steel, offering a great weight reduction benefit.
What is the primary benefit of the nylon insert?
The nylon insert creates friction against the bolt threads, which prevents the nut from backing off due to mechanical vibration.
How many nuts are in one pack?
Each pack contains 5 individual nuts.
Troubleshooting
Nut is difficult to thread onto the bolt
Ensure the threads are clean and free of debris. Verify that you are using the correct pitch and diameter to match your existing bolt.
Anodised finish is scratching during installation
Use a socket with a nylon insert or wrap the nut in a thin layer of tape before using your tools to protect the finish.
Nut feels loose after vibration
Ensure the nylon insert is still intact. If the nut has been tightened and removed multiple times, the nylon may wear down and lose its locking effectiveness; replace if necessary.
Pros and Cons
Pros
- Significantly lighter than steel or titanium equivalents
- Vibrant blue anodised finish provides a clean, custom look
- Resistant to road salt and common environmental corrosion
- Nyloc insert prevents loosening due to vehicle vibration
Cons
- Not suitable for high-stress or safety-critical mounting points
- Softer material than steel, requiring care during installation
- Limited to non-load bearing applications
Setup, Compatibility & Care
When installing your Pro-Bolt Alloy Nyloc Nuts, always use a high-quality socket or wrench to avoid marring the anodised surface. Since aluminium is softer than steel, avoid over-tightening. It is recommended to apply a small amount of anti-seize lubricant to the bolt threads to prevent galvanic corrosion between dissimilar metals. Regularly inspect the anodised finish during routine maintenance; while the coating is durable, heavy abrasion from road debris can eventually wear through the layer. If the finish is damaged, check the threads for signs of fatigue or stress to ensure they still seat correctly.
