    The nylon insert inside these nuts grips screws so they won't back out or loosen. Use them to keep thin parts fastened on engines and other vibrating machinery.
    Steel—Best for dry environments since moisture will cause these nuts to rust.
    Cadmium Yellow-Chromate-Plated Steel—Thread fasteners on these nuts smoothly without sticking. The plating also creates a stronger barrier against rust than zinc.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these nuts resist rust and mild chemicals.

    Fasten together unaligned parts and keep screws in place. The threaded hole within these press-fit nuts shifts up to .01" in any direction, so you can fasten together thin panels with off-center holes. The irregularly shaped threads tightly grip screws to prevent them from loosening or backing out under vibration.
