FAQs
Can I use these on my brake calipers?
No. These are for non-safety critical applications only and should never be used on high-stress components like brakes or suspension.
Are these nuts reusable?
While the nylon insert may retain some effectiveness, it is generally recommended to use new nuts after removal to ensure the locking function remains secure.
What tools should I use to install these?
Use standard box-end wrenches or sockets. Avoid impact drivers as they can easily damage the softer aluminum threads.
Will these rust in the rain?
No, the anodized finish is highly resistant to water, road salt, and typical environmental conditions.
Why are these so much lighter than my stock nuts?
They are manufactured from a high-grade aluminum alloy, which provides a massive weight savings compared to the heavy steel nuts often used by manufacturers.
Troubleshooting
Nut feels very stiff when starting to thread
This is likely the nylon insert engaging. Ensure the thread pitch is correct and use a wrench to gently turn the nut onto the bolt.
Nut finish showing signs of wear
Ensure you are using the correct size tool to prevent scratching the anodized coating during installation.
Difficulty threading onto a non-Pro-Bolt bolt
Check that the thread pitch and diameter match your bolt exactly. Use of non-standard bolts can lead to thread damage.

Setup, Compatibility & Care
Installation requires basic hand tools. When tightening, use a properly sized wrench or socket and proceed with moderate torque. Since these are made from aluminum alloy, they are softer than steel; avoid using impact guns or excessive force to prevent stripping the threads. For care, avoid using harsh alkaline cleaners or heavy degreasers, which can degrade the anodized finish over time. Simply wiping with a soft cloth and mild soapy water will keep the finish looking new. Always verify the thread size of your existing bolts before purchase to ensure compatibility.
