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

Product Description

The GIBRALTAR MSSW10-5-G is a standard-length threaded spring plunger with an M8 x 1.25 thread size and a stainless steel body and nose. The plunger delivers an initial end force of 5.62 pounds and a final end force of 15.74 pounds, making it suitable for light-to-medium indexing, positioning, and detent applications. Thread length measures 0.866 inches, the plunger projection is 0.118 inches, and the maximum plunger diameter is 0.138 inches. This part is installed by machinists, toolmakers, and mechanical assembly technicians working in production fixtures, jigs, and precision equipment.

This spring plunger is designed for use in threaded bores on machine components, fixtures, and assemblies where repeatable positioning or light retention force is required. Its all-stainless construction makes it appropriate for environments where corrosion resistance matters, including washdown areas, food-adjacent equipment, and outdoor or humid industrial settings. The compact M8 thread size fits standard metric tapped holes found across a wide range of fabricated components and OEM assemblies.

Key Features

• Standard plunger length type with a 0.866 inch thread and body length
• No locking element, allowing straightforward installation and removal

Compatibility

Designed as a direct-fit replacement or new-installation spring plunger for any assembly requiring an M8 x 1.25 threaded bore with a standard-length stainless steel plunger.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a hex key or appropriate driver in a properly tapped M8 x 1.25 through or blind hole. Ensure the mating bore is clean and free of chips or debris before threading the plunger in. De-energize or lock out any moving machinery before servicing fixtures or assemblies containing this component. Do not overtighten, as this can compress the internal spring beyond its working range and reduce retention force.
