Wheel Nut Indicator – WS21YEXT

Wheel Nut Indicator not only provides real time, between service constant visual indication of LOOSENING wheels and OVERHEATING brakes but additionally protects the stud thread. The extended versions are designed to fit vehicles with recessed nuts or trucks with front wheel trims.

For cost-efficient, effective and proactive fleet maintenance and increased safety, your wheel safety product must, at the very least, provide an indication of these issues between scheduled maintenance checks. This allows for timely scheduled intervention, minimizing expensive part replacement and unscheduled downtime.
