These nylon insert stop & lock nuts are ideal to securely fasten a bolt when connecting materials. Use these hexagonal nuts with bolts 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. The nylon insert also helps resist vibration and adds extra corrosion resistance.

• Use for fastening to a bolt when mechanically joining materials
