Spring Plungers Inch

Plunger tips are color coded to indicate light or heavy force: White = Delrin Tip, Light Force Blue = Delrin Tip, Heavy Force • Material: Body – Low Carbon Steel, Black Oxide or 303-Stainless Steel Tip – Delrin • Thread: 2A-UNC • 3D Solid Models are available in multiple formats from www.jergensinc.com • Conforms to TCMA dimensional standards • Patch-Style locking element

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