Frequently Asked Questions
Will these lock nuts prevent my wheels from loosening?
Lock nuts add friction to the thread engagement, so they resist vibration-induced loosening better than standard nuts alone. That said, proper torque to spec is still your first line of defense—lock nuts are a backup, not a replacement for correct installation.
Do I need anything else to install these on my wheels?
These are direct replacements for your factory lug nuts—no additional hardware needed. Just swap them out. Make sure your studs are clean and intact before threading on.
Will the acorn shape fit under my wheel center cap?
Acorn nuts are designed to tuck under most aftermarket caps and sit flush with the wheel. If you're running factory caps or very tight-fitting covers, test fit one nut first to confirm clearance.
