A combined wheel nut indicator and dust cap, designed for wheels without trims or nut rings. It provides an instant visual reference for wheel nut movement and overheating, while also shielding nuts from weathering, corrosion and general road damage.
Widely used across fleets, this type of indicator improves safety, reduces maintenance costs, and helps extend the service life of wheel studs and nuts.
