Jergens 26603 Threaded Spring Plunger 10-32 Steel

Product Description

The JERGENS 26603 is a short-body threaded spring plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The plunger features a 10-32 thread size with a 9/16 inch thread length and a maximum plunger diameter of 0.093 inches. It delivers 0.5 pounds of initial end force and 5 pounds of final end force, making it suitable for applications that require controlled resistance without excessive loading. Both the body and nose are steel construction with a black finish, offering durability in typical shop and industrial environments. This part is installed by machinists, tool builders, and mechanical assembly technicians.

The JERGENS 26603 is used in tooling fixtures, jigs, machine components, and precision assemblies where repeatable positioning or light detent action is needed. The short plunger length type and 1/8 inch projection make it well suited for compact installations where clearance is limited. It is a direct-threaded component that installs into a tapped hole and requires no locking element.

Key Features

• 10-32 thread size with 9/16 inch thread length for standard tapped-hole installation
• Short plunger body style at 9/16 inch body length for compact fitment
• 0.093 inch maximum plunger diameter with 1/8 inch projection
• 0.5 lb initial end force and 5 lb final end force for light-duty detent applications
• Steel body and steel nose with black finish for corrosion resistance in general industrial use
• No locking element - installs and adjusts easily with standard tools

Compatibility

Designed as a standard threaded spring plunger for use in any fixture, jig, or mechanical assembly with a tapped 10-32 hole requiring a short-body detent or positioning element.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a standard hex wrench or driver matched to the plunger body. Ensure the receiving hole is tapped to 10-32 specification and is clean and free of debris before threading in the plunger. De-energize or lock out any powered equipment before servicing assemblies that contain spring plungers. Do not overtighten, as this can deform the plunger body or restrict plunger travel.
