Jergens 30523 Threaded Spring Plunger 10-32 3/4 in

Product Description

The JERGENS 30523 is a standard threaded spring plunger designed for indexing, positioning, and light-duty detent applications in industrial assemblies. The body is machined from steel with a black finish and features a Delrin nose for smooth, low-friction contact. Thread size is 10-32 with a 3/4-inch thread length. The plunger delivers 2.9 pounds of initial end force and 11.1 pounds of final end force, making it suited for consistent, repeatable positioning under moderate load. A locking element is included to secure the plunger in position after installation. This part is installed by machinists, toolmakers, and maintenance technicians working on jigs, fixtures, machine guards, and precision assemblies.

The JERGENS 30523 fits into tapped 10-32 threaded holes in ferrous and non-ferrous components. It is commonly used in fixture plates, index mechanisms, panel latches, and tooling assemblies where controlled spring tension and repeatable plunger engagement are required. The 3/4-inch body length and 1/8-inch plunger projection keep the overall envelope compact, allowing installation in space-constrained assemblies. Suitable for both production tooling and maintenance-repair applications in light industrial and machine shop environments.

Key Features

• 10-32 thread size with 3/4-inch thread length for standard tapped-hole installation
• Steel body with black finish for corrosion resistance in shop environments
• Delrin nose material reduces friction and wear at the contact point
• Locking element secures plunger depth after adjustment
• 2.9-pound initial end force and 11.1-pound final end force for moderate detent applications
• Compact 1/8-inch plunger projection suits tight-clearance assemblies

Compatibility

Designed for installation into standard 10-32 tapped holes in industrial fixtures, jigs, tooling plates, and mechanical assemblies requiring spring-loaded positioning or detent action.

Installation Notes

Installation requires a standard hex wrench sized for a 3/32-inch hex drive. De-energize or lock out any machine or assembly before installing or adjusting the plunger. Thread the plunger into the tapped hole by hand first to avoid cross-threading, then torque using the hex drive. The locking element should be engaged after the plunger is set to the desired projection depth to prevent backing out during operation.
