Threaded Insert Fastener Metric Keylocking Threaded Repair Inserts
Keylocking Thread Inserts are solid inserts that are threaded both internally and externally with keys attached to the top of the insert.
After the insert has been screwed into the parent material, 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.
