M14 X 1.25 X 16.8mm Time-Sert Spark Plug Insert Part # 44111

TIME-SERT is a sophisticated thread repair system that is considered by many to be superior to any other method of repairing stripped or damaged threads. TIME-SERT is a solid bushing insert. This facilitates easy installation and allows for full torque to be applied to repaired threads, ensuring a strong, permanent repair. TIME-SERT is thin walled due to synchronized internal / external threads. Small outer diameter allows for installation in areas where clearance is critical. TIME-SERT is self-positioning. The flange on the top of the insert will insure that the insert cannot wind down into the newly repaired hole. TIME-SERT is self locking. On installation the bottom internal threads of the insert expand to lock the insert in place.
