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

Product Description

The GIBRALTAR SWN10-4BHYZ-PTG is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 1/4-20 threaded body measuring 0.531 inches in length, with a 0.125-inch diameter nylon ball and a maximum ball reach of 0.035 inches. The steel body carries a zinc finish for corrosion resistance, and an integrated locking element secures the plunger in position after installation. Initial end force is 4 pounds, with a final end force of 12 pounds, making it suitable for low-force detent work. Machinists, maintenance technicians, and mechanical assemblers commonly install this type of component.

This ball plunger is used in fixtures, jigs, machine tool components, and light mechanical assemblies where a spring-loaded detent or positioning point is required. The nylon ball reduces wear on mating surfaces and is appropriate for applications where metal-to-metal contact is undesirable. The 1/4-20 thread allows installation into standard tapped holes without special tooling. The purple color code identifies this specific force and configuration variant within the product family for quick selection during assembly or replacement.

Key Features

• 1/4-20 threaded body for installation into standard tapped holes
• 0.125-inch diameter nylon ball minimizes wear on mating surfaces
• Steel body with zinc finish for corrosion resistance
• Integrated locking element holds plunger position after installation
• 4-pound initial end force and 12-pound final end force for light-duty detent applications
• Purple color code for fast variant identification

Compatibility

Designed as a direct-fit threaded ball plunger for standard 1/4-20 tapped holes in mechanical fixtures, jigs, and assembly equipment requiring a spring-loaded detent or positioning element.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 1/4-20 hole using an appropriate wrench or hex key on the body flats. Ensure the mating surface is clean and free of debris before seating the plunger. The integrated locking element should be engaged after positioning to prevent loosening from vibration. De-energize or lock out any associated machinery before servicing or replacing ball plungers in live equipment.
