Tangless® threaded inserts provide permanent, wear-resistant screw threads that completely eliminate the need for tang break-off and retrieval. There are two styles of Heli-Coil® tangless® inserts. “Free-Running” tangless® inserts provide a smooth free-running thread. The “Screw-Locking” tangless® insert provides self-locking torque on the male member by a series of “chords” on one or more of the insert coils. With tangless® inserts, no loose tangs are left behind, and they are the solution when foreign object debris (FOD) cannot be present in critical applications. They eliminate the need for tang break-off and tang retrieval and can be easily adjusted or removed after installation.
