Spring Plungers Metric – Delrin Tip

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. • Material: Body – Low Carbon Steel, Black Oxide 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

The hex drive in the rear of the spring plunger is for plunger insertion. Specials available, see page 39 for Plunger Quote Request worksheet.
