About this part

The optional pack of six 175RC Lightweight Aluminum M3 Lock Nuts are a great way to shave off a little weight and add a little flair to your kit. These lock nuts replace the recessed nuts on popular 2wd/4wd buggy hubs/castor blocks. Choose from multiple bright anodized color options for a lightweight and stylish upgrade.

Awful! These are so stupidly easy to over tighten and strip the nylon that you can actually do it by hand. I only ever tighten to touch but these don't have a bite point, they just skip straight to stripped. Even if you "secure" them they come loose during a race. I bought some generic ones from home Depot that are aren't as pretty but are far superior.
