Australian Made High Temperature Wheel Nut Indicator / Restrainer – White

Manufactured from specialised high-temperature-resistant material, these white indicators are rated to 150°C, compared with standard yellow indicators rated to 123°C. This higher temperature rating makes them particularly suitable for commercial and fleet vehicles operating in applications where frequent braking can generate elevated wheel and brake temperatures.

In addition to monitoring wheel nut movement, the indicators can provide a visible warning of excessive heat. At their specified temperature threshold, the material begins to melt, providing an indication that unusually high temperatures have been experienced around the wheel assembly and that further inspection may be required.

Their indicator/restrainer design also provides a clear visual reference for detecting wheel nut movement while offering additional restraint to help prevent a loosened nut from becoming completely detached.
