Stainless Steel Spring Plungers 30491

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.
