Description:

Key Locking Thread Inserts are an ideal solution to repair stripped, damaged and worn threads or to provide thread reinforcement in a weaker parent material, especially when the mating stud or bolt will be removed frequently.  They provide strong, permanent threads in virtually any material - ferrous, non-ferrous, or non-metallic.  The insert's locking keys are driven down into the tapped threads of the parent material during installation creating a positive mechanical lock that prevents rotation due to vibration or torsion.
  Their external thread design provide maximum pull-out strength with a minimal outside diameter.

Features:
  • Only Standard Drill and Tap required.
  • Can be used in most materials...aluminum, magnesium, cast iron, carbon steel, stainless steel and plastic.
  • Simple installation compared to helical wire inserts.
  • Nearly impossible for the insert to turn after installation.
  • Nearly impossible to cross thread while installing.
  • Adhesive not required to hold insert in place.
  • Rarely affected by hot or cold temperatures because it is held in place mechanically.
  • Easy to remove.
