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. Features & Benefits: - Single-unit construction for better reliability - No set screw to separate from the plunger body - No need for “easy-out” tools - Close tolerance between tip and body - Conforms to TCMA dimensional standards - Patch-style locking element - Hex drive in the rear for spring plunger insertion - Special materials and sizes available upon requests Material Specifications: - Body Material: Low Carbon Steel - Body Finish: Black Oxide - Tip Material: Delrin - Thread: 2A-UNC - Plunger tips are color coded to indicate light or heavy force: White: Delrin Tip, Light Force Blue: Delrin Tip, Heavy Force - White: Delrin Tip, Light Force - Blue: Delrin Tip, Heavy Force Note(s): For easy insertion of Spring Plungers with locking elements, the tapped hole should be countersunk at least 0.030-0.045" (0.76mm-1.14mm) larger than the major diameter of the plunger.
