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:

Can be used in most materials...aluminum, magnesium, cast iron, carbon steel, stainless steel and plastic.
