Lock Nut, Hillman, Black Chrome, Nylon Insert, 1/4 in x 20

Nylon insert lock nuts are hexagonal nuts used with bolts and washers of the same material, finish and grade. The interior 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.
