Gibraltar SWN10-4B-PT-G Threaded Ball Plunger 1/4-20

Product Description

The GIBRALTAR SWN10-4B-PT-G is a threaded ball plunger designed for positioning, indexing, and light-duty detent applications in mechanical assemblies. The plunger body is constructed from steel with a zinc-plated finish for corrosion resistance. The ball is made from nylon and measures 0.125 inches in diameter, with a maximum ball reach of 0.035 inches and a body length of 0.531 inches. It installs into a standard 1/4-20 threaded hole and delivers an initial end force of 3 pounds and a final end force of 7 pounds. A locking element is included to secure the plunger in position once set. This component is installed by machinists, tool and die technicians, and mechanical assembly technicians.

This ball plunger is suited for use in fixtures, jigs, tooling plates, and precision mechanical assemblies where repeatable part positioning or light retention is required. The 1/4-20 thread size makes it compatible with standard tapped holes found in a wide range of industrial and manufacturing applications. The nylon ball minimizes surface marking on workpieces, making it appropriate for use against finished or soft material surfaces.

Key Features

• Steel body with zinc-plated finish for corrosion resistance
• Nylon ball construction reduces surface marking on contact materials
• 1/4-20 thread for installation in standard tapped holes
• Initial end force of 3 pounds and final end force of 7 pounds for controlled detent feel
• Integrated locking element to hold adjustment position
• Compact body length of 0.531 inches suitable for space-constrained assemblies

Compatibility

Designed for installation into standard 1/4-20 threaded holes in tooling fixtures, jigs, and mechanical assemblies requiring light-duty ball plunger detent or positioning function.

Installation Notes

Installation requires a properly tapped 1/4-20 threaded hole in the mating component. Engage and tighten the plunger body using an appropriate wrench or hex key, and engage the locking element to prevent rotation during operation. Ensure the bore depth and thread engagement are adequate before applying load. Follow applicable mechanical assembly and tooling standards for your application.
