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 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.

Datasheet Summary
Powered by GS/AI

The Delrin Tip / Steel Spring Plunger, part number 30421, features a single-unit construction that enhances reliability by eliminating the need for a set screw, which can loosen or separate from the plunger body. This design prevents lost springs and the necessity for "easy-out" tools during adjustments. The plunger body is made from low carbon steel with a black oxide finish, while the tip is constructed from Delrin, providing durability and resistance to wear. The product conforms to TCMA dimensional standards and includes a patch-style locking element for secure operation. The plunger is equipped with a hex drive in the rear for easy insertion. It is color-coded to indicate force levels, with white representing light force and blue indicating heavy force. For optimal performance, the tapped hole should be countersunk at least 0.030-0.045 inches larger than the major diameter of the plunger.
