Helical insert
Helical inserts, more commonly known by the trademark Heli-coil, are inserts made of coiled wire. The insert is inserted into a tapped hole that is larger than the desired hole. They are usually over-sized so that they anchor themselves. Some have tangs to install them while others don't. Special tools are required to install the inserts.
