Disc-Lock™ 3-piece Class 10 Safety Wheel Nuts are specifically designed to prevent wheel loss on commercial vehicles. Disc-Lock™ Safety Wheel Nuts have been proven to provide guaranteed performance from the combination of lateral/bending forces placed on wheels during cornering and torsional forces from braking and accelerating.
Disc-Lock™ Safety Wheel Nuts are easy to install and can be used as a direct replacement for standard wheel nuts. They are fitted in exactly the same way as a standard wheel nut but require a larger socket size. It is best to use a specific Disc-Lock™ socket that accurately fits over both the hex-nut and hex-washer however a standard impact type socket can also be used with care.
