1/4-28 Free-Running Repair Insert
Helical Screw Thread Inserts, commonly called by their trade-name Heli-Coil®, are inserts made from diamond shaped coiled wire. The insert is screwed into an internally threaded hole, and the internal surface of the insert provides a threaded surface that is stronger that the parent material. These inserts are usually used as part of a Thread Repair Kit, when the threads of an internally threaded hole are damaged.
