Based in Toronto, Wheel-Check has been in business for over 19 years making “the original loose wheel-nut indicator”. 

Said to be a simple and effective solution, Wheel-Check can identify a loose wheel fastener with a simple visual inspection. When the nuts are properly torqued to specs, the Wheel-Check devices are then placed on the nuts in a uniform pattern. Once a wheel-nut has loosened, there will be an obvious out-of-sequence pattern that will be visible when the driver does his circle check.

Wheel-Checks are also heat sensitive. If there’s a binding brake or seized bearing, the heat is transferred through the stud and nut.  Once the temperature exceeds 120º C (248º F), the Wheel-Check will start to blister around the circumference and eventually start to distort.  

Easy to install, the reuseable Wheel-Checks cost only a few dollars per wheel and pay for themselves in just one unnecessary re-torque procedure.
