Wire thread inserts are helically coiled fastening devices that provide permanent, wear-resistant screw threads that exceed the strength of most parent material; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear.
Threaded inserts are typically used when the object in which a threaded fastener is being installed is made of a soft material. For hard materials, a screw or bolt can be often driven into the object without the need for a threaded insert. A simple solution is to use a threaded insert.
