Gibraltar SWN10-12BP-G Threaded Ball Plunger 5-40

Product Description

The GIBRALTAR SWN10-12BP-G is a threaded ball plunger designed for indexing, positioning, and light-duty latch applications in mechanical assemblies. It features a steel body with a nylon ball, zinc-plated finish, and a 5-40 thread size. 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 it suitable for low-force detent and locating functions. A built-in locking element secures the plunger in position after installation. Machinists, toolmakers, and mechanical assembly technicians are the typical installers of this component.

This ball plunger fits applications where a small threaded detent or positioning element is required in a 5-40 tapped hole. Common use cases include panel assemblies, jigs and fixtures, light machinery, and precision mechanical enclosures where repeatable tactile positioning is needed. The nylon ball minimizes surface marring on mating parts, making it well suited for applications involving delicate or finished surfaces. The zinc-plated steel body provides corrosion resistance in general indoor mechanical environments.

Key Features

• 5-40 thread size for installation into standard 5-40 tapped holes
• Nylon ball construction reduces marring on mating surfaces
• Steel body with zinc-plated finish for corrosion resistance
• Built-in locking element holds plunger position after installation
• 0.25 lb initial end force and 0.75 lb final end force for light-duty detent applications
• Compact 0.25 inch body length for tight-clearance assemblies

Compatibility

Designed for use in any mechanical assembly requiring a 5-40 threaded ball plunger for indexing, positioning, or light-duty latching functions.

Installation Notes

Install into a pre-tapped 5-40 threaded hole using the appropriate driver or wrench for the plunger head style. Ensure the mating bore is clean and free of debris before threading in the plunger. The locking element should be engaged to prevent the plunger from backing out under vibration. Do not overtighten, as this may restrict ball travel or damage the nylon ball.
