    Wheel Nut Indicator



    wheel nut indicator


    Wheel nut indicators are installed on each wheel nut with each pair of indicators pointing directly at each other. Vehicle operators will notice when any nuts are out of alignment, preventing the possibility of wheel detachment. This simple system provides a clear visual pattern for the driver, indicating which wheel nuts need tightening. A simple solution to preventing a catastrophic or unforeseen event on the road, providing ultimate safety and peace of mind for your drivers.

    Wheel nut indictors are growing in popularity as a cheap, simple and effective method to monitor nuts. They come in many forms and functions but will not negate the need to periodically check the nut tension. Their functions will vary, but could include:

    • To primarily provide a clear visual indication of nut movement
    • Provide a wheel nut retaining function to reduce wheel nut loosening and reduce the likelihood of wheel nuts from completely backing off the wheel hub.
    • Provide an indication of wheel overheating which is otherwise difficult to detect, usually as a result of brakes sticking or problems with the bearings, through the use of specific product material melting points.
    • Provide a clear visual commitment to roadworthiness and professionalism to other road users, customers, health and safety, road and transportation departments.


    • High durable and tough
    • Cost effective way to monitor wheel nut tightness
    • System lock nuts for truck mining operations
    • Essential element for trucks safety
    • Easy to install and use
