Gibraltar SSWN10-11B-G Threaded Ball Plunger 4-48

Product Description

The GIBRALTAR SSWN10-11B-G is a threaded ball plunger designed for light-duty positioning, indexing, and detent applications in mechanical assemblies. The plunger features a stainless steel body with a nylon ball and a 4-48 thread size. The ball diameter measures 0.062 inches, the body length is 0.187 inches, and the maximum ball reach is 0.02 inches. Initial end force is 0.13 pounds and final end force is 0.50 pounds. This compact fastener hardware is typically installed by machinists, maintenance technicians, and mechanical assembly professionals in precision equipment and fixture work.

This ball plunger is suited for applications requiring a small, threaded detent or positioning element in tight spaces. The 4-48 thread size makes it appropriate for fine-pitch tapped holes in light mechanical assemblies, jigs, fixtures, tooling plates, and similar setups where controlled spring-loaded ball engagement is needed. The nylon ball provides a non-marring contact surface, making it appropriate for use against softer or finished workpiece surfaces.

Key Features

• 4-48 thread size for fine-pitch tapped hole installation
• Stainless steel body for corrosion resistance in demanding environments
• Nylon ball provides non-marring contact against workpiece surfaces
• 0.062 inch ball diameter with 0.02 inch maximum ball reach
• Light spring forces: 0.13 lb initial end force and 0.50 lb final end force
• No locking element — straightforward threaded installation

Compatibility

Designed as a standard threaded ball plunger for use in 4-48 tapped holes in mechanical assemblies, jigs, fixtures, and tooling applications requiring light-duty spring-loaded detent or positioning function.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 4-48 hole using an appropriate driver or wrench on the body. Ensure the mating hole thread is clean and correctly tapped before installation to avoid cross-threading. No locking element is included, so thread-locking compound may be applied if retention under vibration is required. Handle the nylon ball carefully during installation to avoid damage to the contact surface.
