Sherex Fastening Solutions, LLC - Disc-Lock™ Heavy Hex Nuts

The Disc-Lock™ Heavy Hex Nut uses the same patented technology as our two and three piece locking nuts. When the assembly is subjected to vibration and/or shock, the interlocking cams attempt to rise against each other. Since the cam rise angles are greater than the pitch angle of the threads, the assembly locks and maintains the clamp load of the bolted connection, thereby maintaining joint integrity.

Safety Wheel Nut	N/A Disc-Lock™'s three piece wedge locking nut in size M22 – our Safety Wheel Nut - is specifically designed to prevent wheel loss from commercial vehicles such as trucks, trailers and buses. Disc-Lock™ Safety Wheel Nuts have been proven to provide better joint protection than that of standard wheel nuts. The combination of lateral, bending forces on the wheels due to cornering, and torsional forces due to braking and acceleration cause Disc-Lock™ Safety Wheel Nuts to lock, maintaining clamp force. Disc-Lock™'s Safety Wheel Nut consistently performs with class 8.8, Grade 5 bolts.
Installation and Removal	N/A The Disc-Lock™ Safety Wheel Nut is easy to install and remove. It is installed in exactly the same way as a standard wheel nut. Place the socket over the hexagon nut and hexagon flanged washer and tighten or loosen.
