Reduce fleet downtime and costs – increase safety – now. 

Our loose wheel nut indicators and other road transport safety systems help you:

  • Reduce maintenance costs
  • Reduce vehicle downtime
  • Save on cost of parts
  • Reduce employee and public injury
  • Visually detect overheating brakes
  • Turn additional wheel re torquing into a simple visual inspections
Fit the wheel nut indicator on the nuts in a uniform pattern. Any pattern may be used as long as any movement is clearly visible. 
Ensure the wheel nut indicator pointer has room to move and is not aligned against the rim.

General Features:

  • Our Wheel Nut Indicators (WNI) are made in Australia especially for the Australian environment. All our WNI are designed for each particular truck nut size so no chance of loose movement and false indications. Unlike other zip tie, clips, rachet systems out there, our system are easily pushed onto each nut that then fits to all 6 points of a hexagon nut, meaning each indicator is robust and secure.

    They are tough, made from anti-fade UV stabilized polymers and numbered to show you at a glance the nut size. The default colour is a bright safety yellow. They can be cleaned using any available detergent solutions or kerosene and are unaffected by road salts or petrochemicals.

    The edges of the yellow WNI are heat sensitive so will begin to go brown when the nut gets to a temp of 123 to 125 deg Celcius. They provide a service constant visual indication of any loosening wheel nuts and also help indicate overheating brakes or possibly bearing problems ( this one depends on the amount of heat dissipation).

    This generally means if wheel nut is getting this hot, you have a brake or maybe a bearing problem. Again saving your maintenance time and money, with an easy visual pickup.

    There is also a high temp version that can go up to 150 degrees, it is white...same price...but these are normally only used on Garbage Trucks or trucks with history of high brake temperature.

Best to choose your size wheelnut with an exact fitting socket. 

If nut is recessed on rim, easiest to place a screwdriver down the side of bolt to get approx mm of recess depth.
