Self-locking key locking threaded inserts are engineered for high-strength, vibration-resistant precision fastening.

A unique mechanical compression design features mid-thread constriction that firmly grips the mating screw upon installation.
This generates consistent radial clamping resistance for a powerful mechanical lock. It eliminates the need for thread lockers, prevents loosening from vibration, impact, or thermal changes, and offers outstanding torque durability—ideal for thread repair and reinforcement.
