Threaded inserts, also known as threaded bushings, are stainless steel inserts that have been designed to add or repair a threaded hole. These inserts are used to repair broken threads, even from a machine bed to an engine manifold. They are designed with a cross-sectional diamond-shaped pattern and wound in the shape of a spring thread. For easy installation, the inserts are designed to be larger in diameter than the tapped hole and to compress. They give a wear-resistant and long-lasting thread in the parent material that is generally stronger than the original.
Enrgtech offers a selection of excellent thread repair inserts from leading brands, including RS PRO, Bollhoff, Recoil, Calmoc by Alcoa, and Keenserts. These fastenings come in a variety of thread sizes, drill sizes, and thread lengths to suit every repair application you need.

It is just a simple process to install it. First, by simply drilling out the previous damaged thread, and tamping the hole with the tapping tool to match the size of the bolt. Then, using the insert tool, screw in the threaded insert and finally break off the tangs. In addition, it is pertinent to remove the tool and sit back on top of the tang. Tap down sharply and avoid twisting the tang off.
