designed for dampening vibration between the bolt and nut; and also provides a moisture seal. Because the threads of the mating bolt deform but do not cut into the nylon so nylon insert lock nuts may be re-used a limited number of times. These nuts are considered one-way lock nuts because they can only be installed one way, top up. The number of uses will depend on specific application and environment. Please consider calling Grainger to provide that detail.
