NUT INDICATOR

Loose wheel nut indicator.

• Used extensively by the transport industry as an enhancement and development of fleet safety roadworthiness procedures, daily walk-round inspection and defect reporting and scheduled maintenance requirements
• Its use allows accurate monitoring for loose wheel nuts and helps prevent wheel hub damage or the loss of a road wheel should a wheel nut loosen.
• An additional safety feature is its heat sensitivity, when higher than normal operational temperature are reached these nut indicators are designed to melt indicating an imminent bearing failure or braking issues.

Recommended Fitting

The nut indicator is fixed to the wheel nut by gripping the six corners of the hexagon of the wheel nut. When the wheel is being fitted out the pointers should be aligned and set in a recognisable pattern. Should a wheel nut loosen off, the nut indicator has no option but to move with the nut and so break the recognisable pattern that was set, thus indicating the wheel nut has begun to rotate and therefore to loosen.
