Gibraltar 10105-G Threaded Ball Plunger 1/4-20 Stainless Steel

Product Description

The GIBRALTAR 10105-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 1/4-20 thread size, a stainless steel body, and a stainless steel ball measuring 0.125 inches in diameter. The body length is 0.5313 inches (17/32 inches) with a maximum ball reach of 0.035 inches. Initial end force is 3 pounds and final end force is 7 pounds. A locking element is included to secure the plunger in position after installation. This component is installed by machinists, toolmakers, mechanical assemblers, and maintenance technicians working on fixtures, jigs, and precision equipment.

This ball plunger is suited for use in machine tool fixtures, assembly jigs, inspection equipment, and industrial tooling where repeatable positioning or light detent action is required. The stainless steel construction makes it appropriate for environments with exposure to moisture or mild corrosives. It is a threaded-body style, installed directly into a tapped hole in the mating component, making it compatible with a wide range of fabricated and machined assemblies across manufacturing and industrial maintenance settings.

Key Features

• 1/4-20 thread size for direct installation into standard tapped holes
• Stainless steel body and ball for corrosion resistance
• 0.125 inch ball diameter with 0.035 inch maximum ball reach
• 3 pound initial end force and 7 pound final end force for light detent applications
• Integrated locking element to lock plunger position after adjustment
• Color code: Purple for quick field identification

Compatibility

Designed as a standard threaded ball plunger for use in any machined or fabricated component with a 1/4-20 tapped hole requiring light-duty indexing or detent positioning.

Installation Notes

Installation is performed by machinists or mechanical assemblers using standard hand tools. The mating component must have a properly tapped 1/4-20 hole to the correct depth before installation. Ensure the assembly is de-energized and at rest before installing or adjusting the plunger. Do not overtighten, as this can damage the locking element or distort the thread engagement.
