Jergens 26921 Threaded Spring Plunger 6-32 Steel

Product Description

The JERGENS 26921 is a standard threaded spring plunger designed to provide controlled, spring-loaded positioning and retention in mechanical assemblies. The plunger features a 6-32 thread size with a 17/32 inch thread length and a maximum plunger diameter of 0.046 inches. It delivers 1.5 pounds of initial end force and 4.5 pounds of final end force, making it suitable for light-duty indexing and detent applications. The steel body and steel nose provide durability in demanding shop and production environments. A locking element is included to secure the plunger in place once installed.

This spring plunger is used in precision machining fixtures, jigs, tooling plates, and general mechanical assemblies where repeatable positioning or light detent action is needed. The 1/16 inch projection and compact 6-32 thread size make it well suited for small-bore applications in tight-clearance designs. It is typically specified by tooling engineers, machine builders, and maintenance technicians working with production fixtures or positioning components.

Key Features

• 6-32 thread size with 17/32 inch thread length for secure installation in threaded bores
• 1.5 pounds initial end force and 4.5 pounds final end force for controlled spring tension
• Maximum plunger diameter of 0.046 inches for small-bore fitment
• 1/16 inch plunger projection for low-profile detent engagement
• Steel body and steel nose construction for durability in production environments
• Integrated locking element to prevent loosening after installation
• Black finish for corrosion resistance and clean appearance

Compatibility

Designed as an OEM-style replacement or new-build component for threaded spring plunger applications using a standard 6-32 thread size in mechanical fixtures, jigs, and tooling assemblies.

Installation Notes

Installation is performed by tooling technicians or maintenance personnel using a 3/64 inch hex key to drive the plunger into a properly tapped 6-32 threaded bore. De-energize or lock out any powered equipment before servicing assemblies that contain spring plungers. Do not overtighten; the locking element is designed to hold position without excessive torque. Confirm plunger projection and engagement depth are correct for the application before returning the assembly to service.
