Gibraltar 10108-G Threaded Ball Plunger 5/16-18 Ss

Product Description

The GIBRALTAR 10108-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The plunger features a 5/16-18 threaded body measuring 0.578 inches in body length, a stainless steel ball with a 0.156-inch diameter, and a maximum ball reach of 0.04 inches. Initial end force is 4 pounds and final end force is 9 pounds. Both the body and ball are constructed from stainless steel, offering corrosion resistance in demanding environments. A locking element is included to secure the plunger in position once installed. This component is installed by machinists, maintenance technicians, and assembly professionals.

The 10108-G is suited for use in precision mechanical assemblies where repeatable positioning or controlled detent action is required. Typical applications include fixture tooling, jig construction, machine tool components, and light industrial equipment where a spring-loaded ball mechanism must engage and disengage reliably under low to moderate force loads. The stainless steel construction makes it appropriate for applications with exposure to moisture, cleaning agents, or mild corrosives. The 5/16-18 thread size fits standard tapped holes in metal or engineered plastic components.

Key Features

• 5/16-18 threaded body for installation in standard tapped holes
• Stainless steel body and ball for corrosion resistance
• 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 detent engagement
• Integrated locking element to secure plunger position after installation
• Compact body length of 0.578 inches for use in space-constrained assemblies

Compatibility

Designed as a direct-fit threaded ball plunger for any assembly or fixture with a 5/16-18 tapped hole requiring spring-loaded ball detent functionality.

Installation Notes

Installation requires a properly tapped 5/16-18 hole in the receiving component. Use an appropriately sized hex key or spanner wrench to thread the plunger to the required depth before engaging the locking element. Ensure the mating surface or detent groove aligns with the ball travel path before finalizing position. Degrease threads and inspect the bore for burrs or debris prior to installation.
