Gibraltar MSSW10-8BH-G Threaded Ball Plunger M12 X 1.75

Product Description

The GIBRALTAR MSSW10-8BH-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in industrial and mechanical assemblies. It features an M12 x 1.75 threaded body machined from stainless steel, with a stainless steel ball measuring 0.315 inches in diameter. The plunger delivers an initial end force of 16.86 pounds and a final end force of 25.85 pounds, providing reliable spring-loaded retention. With a body length of 0.866 inches and a maximum ball reach of 0.098 inches, this compact plunger fits tight-clearance installations. It is installed by machinists, toolmakers, and maintenance technicians in production machinery, fixtures, and precision assemblies.

This ball plunger is suited for use in machine tool fixtures, jigs, automated equipment, and positioning mechanisms where repeatable detent action is required. The stainless steel construction makes it appropriate for environments exposed to moisture, mild corrosives, or wash-down conditions. It is sold individually and is compatible with any threaded bore tapped to M12 x 1.75 specifications. No locking element is included, so thread-locking compound may be applied if retention under vibration is needed.

Key Features

• M12 x 1.75 threaded body for direct installation into tapped bores
• Stainless steel body and ball for corrosion resistance in demanding environments
• Initial end force of 16.86 pounds and final end force of 25.85 pounds for consistent detent performance
• Ball diameter of 0.315 inches with a maximum ball reach of 0.098 inches
• Compact body length of 0.866 inches suits tight-clearance assemblies
• No locking element — compatible with thread-locking compound when vibration resistance is required

Compatibility

Designed to fit any threaded bore tapped to M12 x 1.75 specifications. Consult fixture or equipment drawings to confirm bore depth and thread engagement requirements before installation.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard hex wrench or spanner suited to the M12 body. Ensure the mating bore is clean and correctly tapped to M12 x 1.75 before threading in the plunger. Do not overtighten, as excessive torque can deform the ball seat or restrict ball travel. If the application involves significant vibration, apply a suitable thread-locking compound to the threads prior to installation.
