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

Product Description

The GIBRALTAR MSSW10-4BH-G is a threaded ball plunger designed for positioning, indexing, and light-duty detenting applications in industrial and mechanical assemblies. The plunger features an M6 x 1 thread, a stainless steel body measuring 0.551 inches in length, and a stainless steel ball with a diameter of 0.137 inches. Initial end force is 6.29 pounds and final end force is 9 pounds, providing consistent, repeatable resistance. The stainless steel construction on both body and ball makes this plunger suitable for environments where corrosion resistance is required. It is typically installed by machinists, toolmakers, or maintenance technicians working on fixtures, jigs, or mechanical assemblies.

This ball plunger is suited for use in precision fixtures, machine tool setups, and general mechanical assemblies where controlled positioning or detenting is needed. The M6 x 1 metric thread allows straightforward installation into tapped holes in a wide range of workholding and assembly components. The purple color code aids in quick identification during assembly and maintenance. No locking element is included, making this a standard spring-loaded plunger configuration appropriate for applications where thread-lock compounds or mechanical locking is handled separately.

Key Features

• M6 x 1 metric thread for direct installation into standard tapped holes
• Stainless steel body and ball for corrosion resistance in demanding environments
• 0.137-inch ball diameter with a maximum ball reach of 0.039 inches
• 6.29-pound initial end force and 9-pound final end force for consistent detenting action
• Purple color code for easy identification during assembly
• No locking element — compatible with standard thread-locking methods

Compatibility

Designed as a standard metric threaded ball plunger for use in fixtures, jigs, machine tool components, and general mechanical assemblies requiring an M6 x 1 threaded positioning element.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped M6 x 1 hole using an appropriate hex key or spanner tool. Ensure the mating hole is clean and free of debris before installation. If permanent retention is required, apply a thread-locking compound rated for the operating load. Do not overtighten, as excessive torque may damage the spring mechanism or ball seat.
