Gibraltar 10004BP Threaded Ball Plunger 8-36 Steel

Product Description

The GIBRALTAR 10004BP is a threaded ball plunger designed for positioning, indexing, and light-duty detent applications in mechanical assemblies. The plunger features an 8-36 thread, a steel body, and a steel ball with a diameter of 0.093 inches. Body length is 0.3438 inches (11/32 inches), and the maximum ball reach is 0.025 inches. Initial end force is 0.50 pounds and final end force is 1.25 pounds. This type of component is typically installed by machinists, maintenance technicians, and mechanical assemblers working on fixtures, jigs, tooling, and precision equipment.

The 10004BP is suited for applications requiring repeatable spring-loaded ball engagement in tight-tolerance assemblies. The compact 8-36 threaded body allows installation in thin panels, small fixtures, and close-quarter tooling setups where standard larger-thread plungers will not fit. The purple color code aids in visual identification during component selection and assembly. This plunger is appropriate for both light industrial and instrumentation environments where controlled detent force is needed.

Key Features

• 8-36 thread size for compact, tight-space installations
• Steel body and steel ball for durability in mechanical service
• 0.093 inch ball diameter with 0.025 inch maximum ball reach
• Initial end force of 0.50 pounds, final end force of 1.25 pounds
• Purple color code for easy visual identification
• No locking element — straightforward threaded installation

Compatibility

Designed as a standard threaded ball plunger for use in fixtures, jigs, tooling plates, and mechanical assemblies requiring an 8-36 threaded detent component.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped 8-36 hole using an appropriate driver or wrench on the body flats. Power down or de-energize any associated equipment before servicing the assembly. Avoid over-torquing the small-diameter threaded body, as steel threads in close-tolerance holes can gall or strip. Verify ball reach and force requirements match the application before final installation.
