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

Product Description

The GIBRALTAR MSSW10-5BL-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in industrial and mechanical assemblies. The body and ball are both constructed from stainless steel, making this plunger suitable for environments where corrosion resistance is required. The M8 x 1.25 thread allows direct installation into tapped holes without additional hardware. At 0.196 inches ball diameter and a maximum ball reach of 0.059 inches, this plunger delivers controlled spring tension with an initial end force of 1.12 pounds and a final end force of 2.25 pounds. Machinists, toolmakers, and assembly technicians are the primary installers.

This ball plunger is suited for use in jigs, fixtures, machine tool slides, and precision mechanical assemblies where repeatable positioning or light detent action is needed. The stainless steel construction makes it appropriate for washdown environments, food-adjacent machinery, or any application where carbon steel hardware is not acceptable. The compact body length of 0.63 inches keeps the installed profile low, fitting into tight assemblies where clearance is limited. The purple color code identifies the spring force rating within the product line.

Key Features

• M8 x 1.25 thread for direct installation into standard tapped metric holes
• Stainless steel body and ball for corrosion resistance in demanding environments
• Initial end force of 1.12 pounds and final end force of 2.25 pounds for controlled detent action
• Maximum ball reach of 0.059 inches provides precise, low-travel positioning
• Compact body length of 0.63 inches suits tight assembly clearances
• No locking element — allows field adjustment or removal without additional tools

Compatibility

Designed as a standard metric threaded ball plunger for use in any application requiring an M8 x 1.25 tapped hole for indexing or positioning detent function.

Installation Notes

Installation requires a properly tapped M8 x 1.25 hole in the mating component. Use an appropriate hex key or installation tool on the body to thread in without damaging the ball or spring assembly. Do not overtighten, as excessive torque can deform the body or restrict ball travel. Verify ball reach and spring force are appropriate for the detent load before finalizing installation.
