Wheel-Check can identify a loose wheel nut with a simple visual inspection. When the wheel nuts are properly torqued to specs, the Wheel-Checks are then placed on the wheel nuts in a uniform pattern. If a wheel-nut has loosened, the Wheel-Check will become out of sequence. It will be visible when drivers do their walk around check, according to the company.
Wheel-Checks are heat sensitive. If there is a binding brake or seized bearing, the heat is transferred through the stud and nut. The company says once the temperature exceeds 248º F (120º C), the Wheel-Check will start to blister around the circumference and eventually start to distort.
The company says Wheel-Checks provide a simple, visual means of confirming proper wheel torque in seconds; decrease equipment downtime; cost only a few dollars per wheel; are easy to install; and are available in custom sizes and colors upon request.
