What are spring plungers?

Spring plungers are used for locking and then locating of separate components and come in a variety of metric and standard sizes. These components use spring-force to apply pressure so that the ball or nose will remain positioned. These plungers have different installation methods including hex socket, slotted drive and top slot for blind-holes and have light, standard, or heavy end forces available to them.

What are ball plungers?

Ball Plungers have no knob and a ball instead of a nose. The ball has little depth which allows for movement in and out of position. However, ball plungers do not perform well with heavy loads. Spring plungers are designed to have a nose that allows for movement when side-force is applied. Because of this, spring plungers are not suitable if a heavy side load is involved.
