2 Advantages of TIME-SERT TIME-SERT is a solid bushing insert This guarantees easy installation and allows for full load use of tapped hole, ensuring protection against stress and vibration. TIME-SERT is thinwalled This is due to synchronized internal and external threads. Thin cross sectional area allows for installation in areas of limited space and clearance material. TIME-SERT has positive placement Having a flange on the top of the insert will insure that the insert will have positive placement and cannot wind down into the newly repaired hole. TIME-SERT is self locking On installation the bottom internal threads of the insert are cold rolled to expand the mating external threads into the base material locking the insert in place. Locking mechanism is at the bottom of the insert.
