Lock Nut Fastener Options

  • Nylon Insert Lock Nuts
    • Also known as a Nyloc nut, nylon insert lock nuts are a nylon/steel threaded hex nut that resists vibration or motion. Nyloc nuts can be reused and used in applications requiring performance in high-temperature applications.
  • All Metal Lock Nuts
    • Made with no nylon, all metal lock nuts can withstand high-temperature and high-vibration environments. All metal lock nuts are ideal for automotive, aerospace, military, and turbine applications.
