Description
Overview:
The 25mm Wheel Nut Indicator is a simple, effective safety aid for quickly spotting loosening wheel nuts on road and off‐highway vehicles. Moulded from durable, high‐visibility yellow plastic, it pushes onto the hex of a wheel nut to create a clear visual reference. When aligned in a uniform pattern, any movement of a nut becomes easy to see at a glance. Designed for 25 mm wheel nuts (1 in ≈ 25.4 mm), it suits many HGVs, buses, vans, trailers, and plant or agricultural machinery with exposed wheel nuts. Sold individually for convenient replacements, it supports daily walk‐round checks, especially after tyre changes or heavy use. Manufacturer Part Number: 310 025. A practical, low‐cost addition to routine maintenance that helps improve safety and reduce the risk of wheel loss.
