Gibraltar MSSW10-4B-G Threaded Ball Plunger M6 X 1

Product Description

The GIBRALTAR MSSW10-4B-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in industrial and mechanical assemblies. It features an M6 x 1 thread, a stainless steel body, and a stainless steel ball measuring 0.137 inches in diameter. The body length is 0.551 inches, with a maximum ball reach of 0.039 inches. Initial end force is 2.02 pounds and final end force is 2.92 pounds, making it suited for light spring-loaded detent work. This part is installed by machinists, toolmakers, and mechanical assembly technicians.

This ball plunger is used in fixture plates, jigs, tooling assemblies, and positioning mechanisms where a small, repeatable detent or locating force is needed. The stainless steel construction makes it appropriate for environments where corrosion resistance is a consideration, such as food-grade equipment, wet environments, or cleanroom-adjacent tooling. It installs directly into threaded bores and requires no locking element, keeping the assembly compact and straightforward.

Key Features

• M6 x 1 thread for direct installation into standard metric threaded holes
• Stainless steel body and ball for corrosion resistance
• 0.137 inch ball diameter with 0.039 inch maximum ball reach
• 2.02 pound initial end force and 2.92 pound final end force for light detent applications
• No locking element — compact, low-profile design
• Color code: Purple for quick identification in multi-plunger assemblies

Compatibility

Designed as a standard metric threaded ball plunger for use in any fixture, jig, or mechanical assembly that accepts an M6 x 1 threaded bore.

Installation Notes

Installation requires a properly tapped M6 x 1 threaded hole in the mating component. Use an appropriate hex key or installation tool sized for the plunger body to avoid damaging the ball or spring mechanism. Ensure the bore is clean and free of chips before threading the plunger in. Do not overtighten, as this can compress the spring beyond its designed travel range.
