Gibraltar 10118 Threaded Ball Plunger 5/8-11 Ss

Product Description

The GIBRALTAR 10118 is a threaded ball plunger designed for use in positioning, indexing, and light-duty locking applications across mechanical assemblies. The plunger features a 5/8-11 thread, a stainless steel ball measuring 0.375 inches in diameter, and a stainless steel body with an overall body length of 63/64 inches (0.9844 inches). A built-in locking element secures the plunger in place after installation, preventing loosening from vibration. Initial end force is 7 pounds, with a final end force of 50 pounds, giving technicians a defined force progression for repeatable positioning performance.

This ball plunger is suited for use in machine tools, fixtures, jigs, and industrial equipment where a spring-loaded detent or indexing point is required. The all-stainless steel construction makes it appropriate for applications where corrosion resistance is a priority, such as wet environments, food-adjacent machinery, or chemical-exposure settings. The 5/8-11 thread is a standard coarse thread, commonly found in mid-size mechanical and industrial hardware applications.

Key Features

• 5/8-11 threaded body for installation into standard tapped holes
• Stainless steel ball and body construction for corrosion resistance
• Ball diameter of 0.375 inches with a maximum ball reach of 0.096 inches
• 7-pound initial end force and 50-pound final end force for reliable detent action
• Integrated locking element prevents backing out under vibration
• Color code: Purple for quick field identification

Compatibility

Designed as a standard-thread ball plunger for use in fixtures, jigs, machine tools, and industrial assemblies requiring a 5/8-11 threaded detent or indexing component.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 5/8-11 hole using an appropriate wrench or hex tool on the body flats. Power down or de-energize any equipment before servicing mechanical assemblies. The locking element should be engaged fully to prevent movement under load or vibration. Do not overtighten, as this can deform the ball seat or restrict ball travel.
