Gibraltar SWN10-4BHYZ-G Threaded Ball Plunger 1/4-20

Product Description

The GIBRALTAR SWN10-4BHYZ-G is a threaded ball plunger designed for indexing, positioning, and light-duty detenting applications in mechanical assemblies. The body is machined from steel with a zinc finish and houses a nylon ball measuring 0.125 inches in diameter. The body length is 0.531 inches, and the maximum ball reach is 0.035 inches. Initial end force is 4 pounds, with a final end force of 12 pounds. This plunger is installed by maintenance technicians, tool-and-die workers, and mechanical assemblers wherever controlled, repeatable ball engagement is required.

This ball plunger is suited for use in jigs, fixtures, machine tools, and light industrial equipment where a threaded retention device is needed to locate or hold a component in position. The 1/4-20 thread size allows installation into standard tapped holes. The nylon ball provides low-friction contact and reduces the risk of marring softer mating surfaces, making it appropriate for applications where surface protection is a consideration.

Key Features

• 1/4-20 threaded body for installation into standard tapped holes
• Steel body with zinc finish for corrosion resistance in general industrial environments
• Nylon ball reduces surface marring on mating components
• 4 pounds initial end force and 12 pounds final end force for light-duty detenting
• Compact 0.531 inches body length fits space-constrained assemblies
• No locking element — installs and adjusts with standard tooling

Compatibility

Designed as a standard 1/4-20 threaded ball plunger for use in jigs, fixtures, and mechanical assemblies requiring a nylon ball contact element and steel threaded body.

Installation Notes

Installation requires a properly tapped 1/4-20 hole in the mating component. De-energize or lockout any machinery before installing or servicing plungers in powered equipment. Use a hex key or appropriate driver to thread the plunger body in to the desired depth; do not overtighten, as the steel body can strip softer tapped materials. Confirm ball travel and engagement force after installation before returning the assembly to service.
