The TRP Loose Wheel Nut Indicator (Checkpoint) Part No. 0865797 is a vital, non-capping safety tool designed for commercial vehicles. It is precisely sized at 24 mm to fit snugly over 24mm hex wheel nuts, providing an indispensable visual means of monitoring wheel security.

Utilizing the Checkpoint principle, this indicator is installed with its tips aligned. If a wheel nut experiences a loss of torque and begins to loosen, the indicator will rotate, instantly breaking the pattern and alerting drivers or maintenance personnel. This immediate visual feedback is essential for conducting rapid pre-trip inspections and preventing catastrophic wheel loss incidents.

The high-visibility Yellow color ensures the status of the wheel nuts can be easily and quickly assessed, even from a distance, reinforcing safety compliance across the fleet.
