Jergens Spring Plungers, unlike conventional spring plungers, are machined in one piece. The spring is assembled from the top so that there is no need for a set screw. Our Spring Plungers do not have a set screw that can loosen or separate from the plunger body. The advantage is no lost springs and no need for “easy-out” tools. When adjusting Solid Drive, you can be sure the plunger body is turning and not a set screw.
