Jergens 26703 Threaded Spring Plunger 10-32 Steel Body

Product Description

The JERGENS 26703 is a short-body threaded spring plunger designed to provide controlled, repeatable positioning force in mechanical assemblies. The plunger features a 10-32 thread size with a 9/16-inch thread length and body length. The nose diameter measures 0.093 inches with a 1/8-inch projection. Initial end force is 0.5 pounds and final end force is 5 pounds, making it well suited for light-duty indexing and positioning applications. The steel body and steel nose are finished in black. A locking element is included to secure the plunger in the threaded bore after installation. This part is typically installed by machinists, toolmakers, or mechanical assembly technicians.

The JERGENS 26703 is used in jigs, fixtures, and machine components where a compact, threaded plunger is needed to hold, locate, or index a workpiece or moving part. Its short plunger length type makes it appropriate for space-constrained assemblies where a standard-length plunger would not fit. The 10-32 threaded body allows installation into a pre-tapped hole in steel, aluminum, or other common tooling materials.

Key Features

• 10-32 thread size with 9/16-inch thread and body length for compact installation
• 0.093-inch maximum plunger diameter with 1/8-inch projection
• 0.5-pound initial end force and 5-pound final end force for light-duty positioning
• Steel body and steel nose with black finish for corrosion resistance in shop environments
• Locking element included to lock plunger position in threaded bore
• Short plunger length type suited for space-restricted fixture and tooling applications

Compatibility

Designed as a direct-fit threaded spring plunger for pre-tapped 10-32 bores in jigs, fixtures, and mechanical assemblies requiring short-body positioning hardware.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 10-32 bore using an appropriate hex key or driver on the locking element. Ensure the bore is clean and free of chips or debris before installation. Engage the locking element to prevent the plunger from backing out under vibration or repeated loading. Do not overtighten, as this can deform the plunger body or damage the thread.
