The driving tangs of HeliCoil screw thread inserts should be removed so as to eliminate their interference with the end of the assembled bolt. Depending on the speed at which the tangs are to be removed, a few types of tang breakers are available.

HeliCoil Tang Break Off Tools are available for use with inserts up to 1/2" and M12 in diameter. For sizes larger than these, use long nosed pliers to remove the tang from the insert.
