Gibraltar MSSW10-5-PT-G Threaded Spring Plunger M8 X 1.25

Product Description

The GIBRALTAR MSSW10-5-PT-G is a threaded spring plunger designed for indexing, positioning, and locating applications in mechanical assemblies. The body and nose are both constructed from stainless steel, making it suitable for environments where corrosion resistance is required. It features an M8 x 1.25 thread with a 0.866 inch thread length and a standard-length plunger projecting 0.118 inches. Initial end force is 5.62 pounds and final end force is 15.74 pounds. A locking element is incorporated into the design to secure the plunger position once set. This component is installed by machinists, toolmakers, and mechanical assembly technicians.

This spring plunger is used in jigs, fixtures, tooling plates, and machine assemblies where repeatable part positioning or light-duty detent action is needed. The M8 x 1.25 thread size makes it compatible with standard metric threaded bores found in industrial tooling and equipment. It is suited for both light production and precision fixture applications where a compact, corrosion-resistant plunger is required. The stainless steel construction supports use in washdown or high-humidity environments.

Key Features

• Stainless steel body and nose for corrosion resistance in demanding environments
• M8 x 1.25 thread for compatibility with standard metric threaded bores
• Locking element allows the plunger to be fixed at a set position
• 5.62 pound initial end force and 15.74 pound final end force for consistent detent action
• Standard plunger length of 0.866 inches with 0.118 inch projection
• Maximum plunger diameter of 0.138 inches for precise fitment in close-tolerance applications

Compatibility

Designed as a standard metric threaded spring plunger for use in industrial jigs, fixtures, tooling plates, and mechanical assemblies requiring an M8 x 1.25 threaded bore.

Installation Notes

Installation is typically performed by machinists or mechanical assembly technicians using a hex key or spanner wrench sized for the plunger body. Ensure the mating threaded bore is clean and free of debris before installation. The locking element should be engaged after the plunger is positioned to the desired depth to prevent rotation during operation. Power down or de-energize any associated equipment before servicing components in the assembly.
