Gibraltar SWN10-8B-PT-G Threaded Ball Plunger 1/2-13

Product Description

The GIBRALTAR SWN10-8B-PT-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 1/2-13 thread size, a steel body with a zinc-plated finish, and a nylon ball measuring 0.281 inches in diameter. The body length is 0.750 inches with a maximum ball reach of 0.072 inches. Initial end force is 6 pounds and final end force is 12 pounds. A locking element is included to secure the plunger in position after installation. This part is typically installed by machinists, millwrights, and mechanical assembly technicians working on fixtures, jigs, and precision equipment.

This ball plunger is suited for use in light industrial and mechanical assembly environments where repeatable positioning or soft detent action is required. The nylon ball reduces marring on mating surfaces, making it appropriate for applications where surface protection is a priority. The zinc-plated steel body provides corrosion resistance for general shop and indoor industrial environments. It is sold individually and is well-suited for fixture building, tool and die work, and OEM assembly applications.

Key Features

• 1/2-13 thread size for standard tapped-hole installation
• Nylon ball (0.281 inches diameter) minimizes surface marking on mating parts
• Steel body with zinc-plated finish for corrosion resistance
• 6-pound initial end force and 12-pound final end force for light detent applications
• Integrated locking element to prevent loosening after installation
• Maximum ball reach of 0.072 inches for controlled engagement depth

Compatibility

Designed as a standard threaded ball plunger for use in tapped holes with 1/2-13 thread specification, suitable for fixture plates, jigs, machine tool components, and OEM mechanical assemblies requiring light-duty indexing or detent action.

Installation Notes

Installation requires a pre-tapped 1/2-13 hole in the mating component. Ensure the assembly is de-energized and stationary before installing or adjusting ball plungers in powered equipment. Use appropriate hand tools and avoid overtightening, as excessive torque can damage the locking element or deform the housing. Verify ball reach and force requirements against the application before final installation.
