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.
