Installation Guide

Installing these wheel nut caps is as simple as it gets. Just align each cap over the wheel nut and press down firmly until it clicks into place. No adhesives, no tools, no mechanical experience required. Remove them just as easily whenever needed for tire rotation or brake service.

Why Protect Your Wheel Nuts?

Exposed wheel bolts are constantly subjected to water, road salt, and debris. Over time, this leads to rust and corrosion that can make nut removal difficult — and even compromise your wheel security. Protecting them with these caps is a simple, low-cost way to maintain your vehicle. For more automotive safety best practices, visit the U.S. Consumer Product Safety Commission (CPSC).
