Jergens 26872 Threaded Spring Plunger M6 X 1 Steel

Product Description

The JERGENS 26872 is a threaded spring plunger designed for indexing, positioning, and light-duty ball-detent applications in machine tooling, fixtures, and assembly equipment. The plunger body and nose are both steel with a black finish, making it suited for environments where durability and corrosion resistance matter. The M6 x 1 thread and 25 mm thread length allow secure installation in standard tapped holes. The spring mechanism delivers an initial end force of 1.35 kg and a final end force of 5.85 kg, providing consistent and repeatable positioning pressure. A 3 mm hex drive simplifies installation with standard tooling.

This spring plunger is used in precision jigs, fixtures, and workholding setups across manufacturing and machining environments. It is suited for OEM machine builders, tool and die shops, and maintenance technicians who need reliable part positioning or soft-stop detent action. The 3.02 mm plunger diameter and 5 mm projection make it appropriate for light-load locating tasks where controlled spring force and compact geometry are required.

Key Features

• M6 x 1 thread with 25 mm thread length for standard tapped-hole installation
• Steel body and steel nose with black finish for durability
• 5 mm plunger projection for controlled detent engagement
• Initial end force of 1.35 kg and final end force of 5.85 kg for consistent positioning

Compatibility

Designed as an OEM-style threaded spring plunger for use in any application requiring an M6 x 1 tapped hole and a compact steel plunger with a 5 mm projection.

Installation Notes

Installation is performed by threading the plunger body into a properly sized and tapped M6 x 1 hole using a 3 mm hex key. Ensure the mating hole is clean and free of debris before threading in the plunger. Do not overtighten, as excessive torque can damage the spring mechanism or thread engagement. No special certifications or permits are typically required for fixture hardware installation.
