Engineered with a multi-size polymer design, this loose wheel nut indicator fits hex, 8-sided, or 10-sided nuts ranging from 1-3/16" (30.2 mm) to 1-1/2" (30 to 38 mm). The chemical-resistant material withstands heat from heavy braking but melts during hub overheating to provide a visual alert of mechanical failure. Furthermore, the non-stick construction allows for tool-free application and clean removal from the wheel assembly if a thermal event occurs.
