Stainless steel nylon insert stop nuts are ideal for securely fastening a bolt when connecting materials. Use these hexagonal nuts with bolts and washers of the same material, finish and grade. The nylon ring inside the nut creates rotational resistance when displaced by a mating male threaded fastener, thus preventing loosening.
- Matches bolts or rods of a 1/2 inch-13 coarse thread size
