Gibraltar 10112-G Threaded Ball Plunger 3/8-16 Stainless

Product Description

The GIBRALTAR 10112-G is a threaded ball plunger designed for positioning, indexing, and light detent applications in industrial and mechanical assemblies. It features a stainless steel body and stainless steel ball with a 3/8-16 thread for direct installation into tapped holes. The ball diameter measures 0.187 inches with a maximum ball reach of 0.048 inches and a body length of 0.625 inches. Initial end force is 6 pounds and final end force is 21 pounds. A locking element is included to secure the plunger in place once set, preventing migration under vibration or repeated cycling.

This ball plunger is suited for use in machine tool fixtures, jigs, dies, and precision mechanical assemblies where repeatable detent action or part positioning is required. The stainless steel construction makes it appropriate for environments where corrosion resistance is a priority, including food processing equipment, washdown areas, and marine-adjacent applications. It installs into any tapped 3/8-16 hole and is typically specified by tool and die makers, machinists, and maintenance technicians working on light-load indexing or positioning mechanisms.

Key Features

• 3/8-16 threaded body for direct installation into standard tapped holes
• Stainless steel body and ball for corrosion resistance in demanding environments
• 0.187 inches ball diameter with 0.048 inches maximum ball reach
• 6 pound initial end force and 21 pound final end force for reliable detent action
• Integrated locking element prevents loosening under vibration
• Compact 0.625 inch body length suits space-constrained assemblies

Compatibility

Designed as a direct-fit threaded ball plunger for any application requiring a 3/8-16 tapped hole installation with stainless steel construction and a locking element.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a hex wrench or spanner tool appropriate for the plunger body. Thread the plunger into a clean, properly tapped 3/8-16 hole and torque to the assembly specification for the application. Engage the locking element once the plunger is positioned correctly to prevent rotation in service. Ensure the mating surface or detent groove is aligned with the ball path before finalizing installation.
