Gibraltar 10012P-G Threaded Ball Plunger 5/16-18 Steel

Product Description

The GIBRALTAR 10012P-G is a threaded ball plunger designed for use in positioning, indexing, and locating applications in mechanical assemblies. It features a 5/16-18 threaded body machined from steel, with a steel ball measuring 0.156 inches in diameter. The ball extends a maximum of 0.04 inches beyond the body face, delivering an initial end force of 4 pounds and a final end force of 9 pounds. The body length is 0.578 inches. This type of component is typically installed by machinists, toolmakers, and maintenance technicians working on fixtures, jigs, and precision mechanical assemblies.

Threaded ball plungers like the 10012P-G are used in industrial and light manufacturing environments where repeatable positioning or spring-loaded retention is required. Common applications include fixture locating, detent mechanisms, and panel or drawer alignment in both production tooling and equipment maintenance contexts. The compact 5/16-18 thread size makes it suitable for installations where space is limited but consistent spring force is still required.

Key Features

• 5/16-18 threaded body for straightforward installation into tapped holes
• Steel body and steel ball for durability in mechanical service
• 0.156 inch ball diameter with 0.04 inch maximum ball reach
• 4 pound initial end force and 9 pound final end force for controlled positioning
• No locking element — standard spring-loaded design
• Color code: Purple for easy identification

Compatibility

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

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped 5/16-18 hole using an appropriate wrench or driver. Ensure the mating bore is clean and free of debris before installation. Do not overtighten, as excessive torque can damage the spring mechanism or distort the body. Always verify that the ball travel and force characteristics are suitable for the specific application before final assembly.
