Gibraltar MSSW10-3BP-G Threaded Ball Plunger M4 X 0.7

Product Description

The GIBRALTAR MSSW10-3BP-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. Featuring an M4 x 0.7 thread, a 0.098-inch stainless steel ball, and a 0.354-inch body length, this plunger delivers a 0.90-pound initial end force and a 2.25-pound final end force. The integrated locking element secures the plunger in place after installation, preventing loosening from vibration or repeated cycling. Both the body and ball are stainless steel, making it suitable for corrosive or wash-down environments. Licensed machinists, tool and die technicians, and mechanical assemblers are the typical installers.

This ball plunger is suited for use in jigs, fixtures, tooling plates, and precision mechanical assemblies where repeatable positioning is required. The M4 x 0.7 metric thread fits standard tapped holes in aluminum, steel, and plastic housings. The maximum ball reach of 0.032 inches and the 2.50 mm ball diameter make it appropriate for fine-tolerance detent and alignment work in light industrial and OEM equipment applications. The purple color code aids in quick identification during assembly or kitting operations.

Key Features

• M4 x 0.7 metric thread for compatibility with standard tapped metric holes
• Stainless steel body and ball for corrosion resistance in demanding environments
• Locking element prevents loosening under vibration or repeated actuation
• 0.90-pound initial end force and 2.25-pound final end force for controlled detent action
• Maximum ball reach of 0.032 inches for fine-tolerance positioning applications
• Purple color code for fast visual identification in assembly and inventory

Compatibility

Designed as an OEM-style threaded ball plunger for use in standard M4 x 0.7 tapped holes in mechanical assemblies, jigs, fixtures, and tooling components.

Installation Notes

Installation is performed by machinists or mechanical assemblers using a standard hex key or driver appropriate for the M4 body. Ensure the mating tapped hole is clean and free of debris before threading in the plunger. The locking element should be engaged fully to prevent back-out during service. Do not exceed the rated ball reach or apply side-loading forces beyond the plunger design envelope.
