Hex lock nuts use a nylon insert at the top of the nut creating tension between the nut and the threads of the mating component. As the nut is threaded onto a shaft or rod, it will spin freely until the threads from the host part engage the nylon insert. The threads of the mating shaft will displace the nylon and create resistance. This resistance prevents unintentional moving of the lock nut. The nylon in traditional hex lock nuts can wear, and become less effective after repeated removal and installation. For optimum holding power, replace the nut if it needs to be removed during disassembly of a component.
