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.

Thin Wall Key Inserts have a smaller external thread size than standard heavy duty inserts, making them the perfect solution for tight spaces where less pull-out strength is acceptable.

Instructions (After Drilling & Tapping):

Engage insert keys into vertical slots of the installation tool.
Screw insert into part and flush with top of the part.
Lift - Rotate tool. Hole fits over the keys. Drive down as far as possible.
Turn tool until timing mark lines up with key. Drive until keys even with top of insert.
