[0033]As shown in FIG. 1, a support structure 20 is formed with a threaded opening 22 having a plurality of threads 24 formed therein. Referring to FIG. 2, a helical coil insert 26 is typically made from a preformed metal wire, typically formed with a diamond cross section, which is wound to form a helical coil having successive convolutions. The coil insert 26 is wound in such a manner that outer threads 28 and inner threads 30 are formed by sharp, generally “V” shaped portions on opposite sides of the diamond cross section on the outer and inner surfaces, respectively, of the insert.

[0034]The size of the outer threads 28 of the coil insert 26 are consistent with the size of the threads 24 of the opening 22 in the support structure 20. The size of the inner threads 30 of the coil insert 26 are consistent with the size of the threads typically formed on a portion of the outer surface of a threaded fastener (not shown), which eventually is to be threadedly mounted in coil insert.
