Lock Nuts

Lock nuts keep a joint tight where vibration would loosen a plain nut. All-metal prevailing-torque types deform the top thread or crown to grip the bolt, so they also work at temperatures where a nylon insert would fail.

  • Works at higher temperatures than nylon insert nuts
  • Reusable a limited number of times
  • Prevailing torque holds position
