The TRP Loose Wheel Nut Indicator, Dustite (Part No. 9510147) is a crucial dual-purpose safety and maintenance component designed for commercial vehicles utilising 19 mm wheel nuts. This indicator serves two essential roles:

1. Visual Safety Indication: The high-visibility Yellow indicator, with its distinctive pointer (Long Reach type), allows drivers and maintenance teams to instantly detect any wheel nut rotation or loosening during a walk-around inspection. Misalignment of the pointers signals a critical torque loss, enabling timely preventive action against wheel detachment.

2. Nut Protection: The Dustite design features a durable cap that covers the wheel nut, sealing it against environmental damage, including dirt, moisture, and road salts. This protection guards against corrosion and assists in maintaining the nut’s integrity for future servicing.

The TRP 9510147 is a simple, cost-effective tool for enhancing fleet safety and ensuring regulatory compliance.
