Definition
A 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 workpiece thereby eliminating a machining operation, or simplify changeover
from unified to metric threads or vice versa.
