These nylon lock nuts are hexagonal nuts used with bolts and washers of the same material, finish, and grade. The nylon ring creates rotational resistance when displaced by a mating male threaded fastener, thus preventing loosening. The nylon insert also helps resist vibration and adds extra corrosion resistance. The package size designates the inner diameter and the number of threads per in. or thread pitches.
