A Spring Plunger, is a compact and thin device used to index and position different components. Once fitted, it exerts sufficient pressure to keep the ball or nose in place. The spring plunger lives true to its name by applying pressure with spring force. This permits the ball to stay in place at all times, regardless of how much pressure is applied to it. Spring plungers can be fitted in a variety of methods, including hex sockets, standard, strong force, and more.
