Abstract: A threaded insert installation tool includes an adapter assembly that connects a front and assembly with a driver. The threaded insert installation tool may be used in areas with limited access and may be operated with a battery-powered screwdriver. The adapter assembly may include a drive shaft that may have a segment square cross-section that may slide in linear direction within a square-hole sleeve assisted by a spring converting the rotary motion provided by the cordless screwdriver into a linear feed. The threaded insert installation tool may be suitable for, but not limited too, applications in the automotive, communication, aerospace, military and defense industries. The threaded insert installation tool may be used to install threaded inserts in tapped holes that are positioned in a space having an extended depth and a close proximity to surrounding walls, such as inside a cylinder or a barrel, for example, a missile shell.
