Thread Insert

Threaded Insert, also known as a Threaded Bushing, is a fastener element that is inserted into an object to add a threaded hole. They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece, thereby eliminating a machining operation, or simplify changeover from unified to metric threads or vice versa.
