Jergens 26824 Threaded Spring Plunger 1/4-20 Steel

Product Description

The JERGENS 26824 is a standard threaded spring plunger designed to provide controlled, spring-loaded contact force in tooling, fixturing, and mechanical positioning applications. With a 1/4-20 thread size and 1 inch thread length, this plunger installs directly into a tapped hole in a workpiece or fixture body. The steel body and steel nose deliver durability in industrial environments. An initial end force of 3 pounds and a final end force of 13 pounds make this plunger suited for light-duty indexing, detent, and component retention tasks. The 3/16 inch projection and 0.119 inch plunger diameter keep the footprint compact for tight fixture layouts. Machinists, toolmakers, and mechanical assemblers typically install and service these components.

This spring plunger is used in jigs, fixtures, and machine tooling where repeatable positioning or light holding force is required. The 1/4-20 thread is a common size found in a wide range of fixture plates, workholding bodies, and mechanical assemblies across manufacturing and industrial maintenance environments. The black finish provides a basic level of surface protection. The standard plunger length type and 1 inch body length make this a straightforward drop-in component for most standard tapped-hole installations without modification.

Installation Notes

Installation requires a properly tapped 1/4-20 hole in the receiving component. Use the 1/8 inch hex key engagement to thread the plunger in by hand or with a hex key to the desired depth. Ensure the receiving bore is clean and free of chips or debris before installation. Always de-energize or lock out any associated equipment before servicing plungers in active fixtures or machinery.
