Gibraltar 10011P-G Threaded Ball Plunger 5/16-18 Steel

Product Description

The GIBRALTAR 10011P-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The plunger features a steel body and steel ball with a black finish, threaded to a 5/16-18 thread size. It delivers an initial end force of 2 pounds and a final end force of 4.5 pounds, making it suitable for low-force retention and locating tasks. The body measures 0.5781 inches in length with a maximum ball reach of 0.04 inches and a ball diameter of 0.156 inches. Machinists, maintenance technicians, and equipment assemblers install this type of plunger into tapped holes in jigs, fixtures, and machine components.

This ball plunger is suited for light industrial and mechanical assembly applications where a spring-loaded ball is needed to hold a moving component in a set position. Typical uses include fixture locating, drawer stop mechanisms, and panel alignment in fabricated assemblies. The 5/16-18 thread allows installation into standard tapped holes common in steel and aluminum tooling. The purple color code aids in quick field identification when multiple plunger specs are in use on the same fixture or assembly station.

Key Features

• Steel body and steel ball construction for durability in industrial environments
• Black finish with purple color code for field identification
• Initial end force of 2 pounds and final end force of 4.5 pounds for light-duty detent use
• Ball diameter of 0.156 inches with a maximum ball reach of 0.04 inches
• No locking element — standard non-locking configuration

Compatibility

Designed as a standard threaded ball plunger for use in tapped 5/16-18 holes in jigs, fixtures, machine components, and fabricated assemblies requiring light-duty spring-loaded ball detent or positioning functions.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 5/16-18 hole using a wrench or hex key, depending on the body style. Ensure the mating hole is clean and tapped to the correct depth to achieve full body engagement. Do not overtighten, as this can restrict ball movement or damage the spring mechanism. Verify ball reach and end force requirements match the application before installation.
