Wheel Nut Indicators 27mm - 100 Pieces

Wheel Nut Indicators (WNI) are used extensively by the road haulage industry as a visual safety aid for enhanced fleet safety.
WNIs clearly identify when a wheel nut has loosened allowing remedial action to be taken before a failure occurs.  

Our WNIs are manufactured to the highest quality using impact co-polymer polypropylene, which gives excellent rigidity and high impact resistance.

The melting point has been engineered to 120 °C, deforming when excessive heat is transferred from the wheel/hub.
