Gibraltar SSWN10-12B-G Threaded Ball Plunger 5-40

Product Description

The GIBRALTAR SSWN10-12B-G is a threaded ball plunger designed for positioning, indexing, and light-duty detent applications in mechanical assemblies. It features a 5-40 threaded body machined from stainless steel with a nylon ball that provides smooth, low-friction contact against mating surfaces. The body measures 0.25 inches in length with a maximum ball reach of 0.02 inches. Initial end force is 0.25 pounds and final end force is 0.75 pounds, making this plunger suitable for applications requiring consistent, repeatable tactile feedback without damaging delicate surfaces.

This ball plunger is used in precision mechanical assemblies, jigs, fixtures, and tooling where a compact detent or positioning element is needed. The 5-40 thread size fits standard tapped holes in light-gauge panels, fixture plates, and small mechanical components. The nylon ball is suited for contact with soft or coated surfaces where a steel ball would cause marking or excessive wear. Installation is performed by machinists, tool and die technicians, or maintenance mechanics working on precision equipment and assemblies.

Key Features

• 5-40 threaded body for installation into standard tapped holes
• Stainless steel body resists corrosion in wet or washdown environments
• Nylon ball provides low-friction, non-marring contact on mating surfaces
• 0.02 inches maximum ball reach for controlled, minimal projection
• 0.25 lb initial end force and 0.75 lb final end force for light-duty detent feel
• Compact 0.25 inch body length suits tight-clearance assemblies

Compatibility

Designed as a standard 5-40 threaded ball plunger for use in tapped holes in mechanical fixtures, jigs, tooling plates, and similar precision assemblies requiring a compact detent or positioning element.

Installation Notes

Install into a properly tapped 5-40 threaded hole using an appropriate hex key or driver; do not overtighten, as excessive torque can deform the small-diameter threaded body. Ensure the mating surface is clean and free of debris before seating the plunger to prevent ball binding. No power lockout is required for typical fixture or tooling applications, but follow any relevant machine-specific lockout procedures when installing in powered equipment.
