The Difference Between Tangless CoilThread inserts And Tanged Inserts

Tangless CoilThread inserts are a helically-coiled, bi-directional, wire design; that install using a drive notch located at either end of the coil insert instead of a tang located at one end of the inserts.

Tangless inserts are identical, in form, fit, and function to conventional tanged inserts (e.g.,CoilThread, Heli-Coil & Recoil). In fact,Tangless CoilThread inserts are identical to tanged inserts in every way except for their method of installation & removal.  Tangless inserts even have the same procurement specification (NASM8846 for unified sizes and MA1565 for metric sizes) as tanged inserts. Tangless inserts eliminate tang break-off and retrieval, are easily adjusted after installation, and offer non-destructive removal.
