Gibraltar 10013-G Threaded Ball Plunger 5/16-18 Steel

Product Description

The GIBRALTAR 10013-G is a threaded ball plunger designed to provide positive positioning and detent action in mechanical assemblies. It features a 5/16-18 threaded body machined from steel with a black finish and a steel ball measuring 0.156 inches in diameter. The body length is 0.578 inches with a maximum ball reach of 0.04 inches. Initial end force is 6 pounds and final end force is 17 pounds. A locking element is incorporated into the design to secure the plunger in position after installation. This part is typically installed by machinists, tool and die makers, or maintenance technicians working on fixtures, jigs, and precision mechanical components.

This ball plunger is suited for use in industrial and mechanical applications where repeatable indexing, positioning, or light-duty detent action is required. Common install scenarios include tooling fixtures, machine slides, panel assemblies, and equipment enclosures where a spring-loaded ball provides controlled resistance at a set position. The steel body and steel ball construction make it appropriate for general-purpose industrial environments.

Key Features

• 5/16-18 threaded body for standard tapped-hole installation
• Steel body with black finish for durability in general industrial use
• Steel ball with 0.156 inch diameter for precise detent contact
• Locking element included to retain adjustment after installation
• 6 pound initial end force and 17 pound final end force for controlled resistance
• Compact 0.578 inch body length for use in tight assemblies

Compatibility

Designed as a standard threaded ball plunger for use in any application requiring a 5/16-18 tapped hole and a spring-loaded detent or positioning element.

Installation Notes

Installation requires a properly tapped 5/16-18 threaded hole in the mating component. Use an appropriate hex key or spanner tool as recommended for the plunger head style. Ensure the mating surface and threaded bore are clean and free of debris before threading in the plunger. The locking element should be set once the desired ball protrusion and force engagement are confirmed.
