JG Spring Plungers
Jergens Spring Plungers | Precision Spring-Loaded Position Control Solutions
JG spring plungers—also called ball plungers or detent plungers—are spring-loaded components used to create a detent, indexing point, or light holding force in fixtures and mechanical assemblies (application dependent). They’re commonly used for positioning adjustable parts, providing “click-stop” engagement, and maintaining repeatable alignment in guards, covers, and modular workholding setups. Because the feel and retention depend on force and tip style, spring plungers are typically selected by specification rather than by general description.

Jergens Solid Drive Plunger is one integral piece of steel: hex drive, plunger, and body. No set screw to separate from plunger body, no lost springs to retrieve, no need for “easy-out” tools. Best of all, when adjusting Solid Drive, you can be sure the spring plunger is turning and not just a set screw.
