how to use helicoil insert properly
Thread the Helicoil insert onto the supplied installation tool and coat the threaded insert with thread locking fluid. Insert the Helicoil threaded insert into the tapped hole and turn the handle of the insertion tool until the top of the Helicoil rests 1/4 to 1/2 of a turn below the surface of the base metal. Place the tang removal tool into the threaded insert and break the tang from the Helicoil insert to lock it in place. Thread the fastener into the Helicoil threaded insert after the thread locking fluid has cured to complete the installation.
