## Description

These nylon insert stop & lock nuts are ideal to securely fasten 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. The nylon insert also helps resist vibration and adds extra corrosion resistance.

• 18-8 stainless steel finish ensures superior corrosion resistance
• Nylon insert resists vibration to keep the nut in place
• 5/8 in.-11 stop nut (pack of 5) for indoor or outdoor projects
