Gibraltar 10015P-G Threaded Ball Plunger 3/8-16 Steel

Product Description

The GIBRALTAR 10015P-G is a threaded ball plunger designed to provide consistent, repeatable indexing and positioning in mechanical assemblies. Featuring a 3/8-16 thread and a steel body with a steel ball, this plunger installs into a tapped hole and uses spring-loaded ball engagement to hold or locate a workpiece or mating component. The ball diameter measures 0.187 inches with a maximum ball reach of 0.048 inches. Initial end force is 5 pounds and final end force is 10 pounds. Machinists, tool and die makers, and maintenance technicians commonly install this type of hardware in jigs, fixtures, and production equipment.

This ball plunger suits light-duty positioning applications in industrial and manufacturing environments. Its 3/8-16 threaded body installs directly into a standard tapped hole, making it a straightforward replacement or new-build component for fixtures, dies, and assembly tooling. The black finish and purple color code aid in identification during assembly and inventory management. It is sold individually and is suited for both OEM production builds and field maintenance tasks.

Installation Notes

Installation requires a properly tapped 3/8-16 hole in the mating component. De-energize or lock out any equipment before servicing assemblies that contain this plunger. Use appropriate thread engagement depth to avoid bottoming out the body, which can affect spring force performance. A hex key or spanner tool may be required depending on the drive style of the body.
