Gibraltar MSSW10-5BH-G Threaded Ball Plunger M8 X 1.25

Product Description

The GIBRALTAR MSSW10-5BH-G is a threaded ball plunger with an M8 x 1.25 thread size, designed to provide controlled spring-loaded positioning, indexing, and light detent holding in mechanical assemblies. The body and ball are both stainless steel, making this plunger suitable for corrosive or washdown environments. With a ball diameter of 0.196 inches and a body length of 0.63 inches, this is a compact unit suited for tight-clearance installations. Initial end force is 9 pounds and final end force is 13.49 pounds, giving technicians and machinists predictable engagement across a repeatable travel range.

This ball plunger is used in manufacturing, tooling, fixture building, and mechanical assembly applications where repeatable part positioning or soft detent action is required. It is installed in threaded bores in jigs, fixtures, machine slides, and similar equipment. The stainless steel construction makes it appropriate for food processing, medical equipment, and other applications requiring corrosion resistance. It is typically installed by machinists, tool and die makers, or maintenance technicians working on precision mechanical assemblies.

Key Features

• M8 x 1.25 thread for direct installation into standard metric threaded bores
• Stainless steel body and ball for corrosion resistance in demanding environments
• 0.196 inch ball diameter with a maximum ball reach of 0.059 inches
• 9 pound initial end force and 13.49 pound final end force for consistent detent engagement
• No locking element — allows field adjustment of spring tension after installation
• Compact 0.63 inch body length fits tight-clearance assemblies

Compatibility

Designed as an OEM-style replacement or direct-install component for metric M8 x 1.25 threaded bores in mechanical jigs, fixtures, slides, and positioning assemblies.

Installation Notes

Installation requires a properly tapped M8 x 1.25 threaded bore in the mating component. Use an appropriate hex key or spanner to seat the plunger body without overtightening, which can restrict ball travel or damage the spring. Verify that the ball extends and retracts freely before final assembly. No locking element is present on this plunger, so thread-locking compound may be applied if a fixed installation depth is required.
