    Safety Wheel Nut - PRODUCT CODE :      
    The DISC-LOCK Safety Wheel Nut is a free spinning, vibration proof wheel nut, specifically designed to prevent wheel loss from commercial vehicles such as trucks, trailers and buses with Hub-Piloted wheel systems.

However, the product can also be used for a wide range of high vibration purposes

   
    How does the DISC-LOCK Safety Wheel Nut work?      
   
 

The DISC-LOCK Safety Wheel Nut is split into two sections, comprising a nut and a hexagon washer. Both sections have interlocking rising cams which are joined together to form one assembly. When subjected to road shock or vibration, the most common causes of wheel loss, the interlocking cams of the DISC-LOCK Safety Wheel Nut rise against each other. As the angle of the cams is greater than the pitch angle of the thread on the stud a wedging action takes place and the DISC-LOCK Safety Wheel Nut locks and will not come loose, thus keeping the wheel on the axle.

DISC-LOCK Safety Wheel Nuts are considered to be far superior in terms of safety than conventional wheel nuts. The shock and vibration which cause existing wheel nuts to come loose, cause DISC-LOCK Safety Wheel Nuts to lock.
