Gibraltar MSW10-3B-G Threaded Ball Plunger M4 X 0.7

Product Description

The GIBRALTAR MSW10-3B-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features an M4 x 0.7 threaded body measuring 0.354 inches in length, with a steel ball diameter of 0.098 inches and a maximum ball reach of 0.032 inches. Initial end force is 0.90 lb and final end force is 2.25 lb, making it well suited for applications requiring controlled, repeatable tactile engagement. Both the body and ball are steel construction. This part is installed by machinists, toolmakers, and mechanical assembly technicians.

The MSW10-3B-G is used in fixtures, jigs, machine tool slides, and precision mechanical assemblies where a spring-loaded ball plunger is needed to locate or retain a moving component at a set position. The M4 x 0.7 thread size fits standard metric threaded bores in light industrial and manufacturing equipment. It is appropriate for both OEM assembly and MRO replacement in production environments.

Key Features

• M4 x 0.7 thread size for direct installation into metric threaded bores
• Steel body and steel ball for durability in industrial service
• 0.098 inch ball diameter with 0.032 inch maximum ball reach
• 0.90 lb initial end force and 2.25 lb final end force for repeatable detent engagement
• Body length of 0.354 inches suits compact installation envelopes
• No locking element, allowing straightforward threaded installation and removal

Compatibility

Designed as a standard metric threaded ball plunger for use in fixtures, jigs, and mechanical assemblies requiring an M4 x 0.7 threaded detent or positioning element.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using an appropriate metric hex key or wrench matched to the plunger body. Ensure the threaded bore is clean and properly tapped to M4 x 0.7 before installation. Do not overtighten, as excessive torque can damage the spring mechanism or thread form. Verify ball travel and engagement force after installation to confirm proper function within the assembly.
