Description
Overview:
The 21mm Long Reach Wheel Nut Indicator and Dust Cap is a push-fit safety cap for monitoring wheel nut movement while shielding the nut from dirt and moisture. Made from a tough, colourfast, high‐temperature resistant polymer in a bright yellow finish, it provides a clear visual pointer to help spot any loosening at a glance. The long-reach body is designed to pass through deep wheel trims and access holes, making checks easier on vehicles where nuts sit recessed. Suitable for road vehicles, trailers, plant machinery and site equipment with exposed wheel nuts, it supports regular inspection routines and helps prevent corrosion on the hex. Size: 21 mm (approx. 0.83 inches). Sold individually. Manufacturer Part Number (MPN): 310 221.
Key Features:
- Dual function: movement indicator plus closed-end dust cap to protect the nut
