Checklink Keeps an Eye on Wheel Nuts
Marketed by Martins Industries, the Checklink combines a wheel nut loosening indicator and a retaining device, allowing it to signal any nut movement while also helping to keep them in place.
The Checklink will also melt to indicate any wheel overheating issue, signaling a problem in the hub or braking system. Depending on the chosen version, the device will melt at either 125 degrees Celsius or 165 degrees Celsius.
This small component is mainly designed for commercial vehicles such as buses and heavy trucks or hazardous material transporters, as well as agricultural vehicles. It proves useful wherever safety-critical fasteners may loosen due to strong vibrations. A simple visual inspection can reveal the presence of a problem.
