Stamped Hex Lock Nuts are removable, reusable threaded fasteners. They can be used alone for load-carrying in light-duty assemblies or to secure standard nuts in high-stress assemblies. This alternative to traditional hex nuts can be used
  • to reduce weight,
  • where screw length is restricted, and/or
  • with a standard hex nut to act as a jam nut.
