Wheel-Check Loose Lug Nut Indicator

Wheel-Checks are a loose lug nut indicator that can identify loose lug nuts with a simple visual inspection.  When the lug nuts are properly torqued to specs, the Wheel-Checks are then placed on the lug nuts in a uniform pattern.  If a lug nut has loosened, the Wheel-Check will become out of sequence.  It will be visible when the driver does his walk around check.  The wheel can then be serviced.

1. Provides a simple, visual means of confirming proper wheel torque in seconds.
2. Reduce your risk of wheel detachment accidents (protect the public, help prevent property and load damage).
3. Lower your maintenance costs by eliminating unnecessary re-torquing.
4. Quickly identify a hot wheel possibly caused by bearing failure or brake drag.
5. Decrease equipment downtime.
6. Facilitates official roadside inspections.
7. Clearly visible at night and in bad weather (rain, snow, muddy conditions).
8. Easy to install.
9. Costs only a few dollars per wheel.
10. Pays for itself in just one avoided re-torque procedure.

Wheel-Checks are plastic with a temperature sensitive polymer finish. They come in bags of 100 pieces in High Visibility Green or High Visibility Red. They are also heat sensitive. If there is a binding brake or seized bearing, the heat is transferred through the stud and nut. If this temperature exceeds 248 deg., the Wheel-Check will start to blister around the circumference and eventually start to distort. for accuracy, please check nut size with a socket wrench. Wheel-Checks are reusable.
