Gibraltar SWN10-1B-G Threaded Ball Plunger 6-40

Product Description

The GIBRALTAR SWN10-1B-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 6-40 thread size, a nylon ball with a 0.078 inch diameter, and a zinc-plated steel body measuring 0.312 inches in length. The nylon ball extends a maximum of 0.023 inches beyond the body face. Initial end force is 0.5 pounds and final end force is 1 pound, making this plunger suited for low-force, repeatable positioning tasks. Machinists, toolmakers, and maintenance technicians typically install these components in jigs, fixtures, and precision assemblies.

This ball plunger is used in light mechanical applications where a small, threaded detent or positioning element is needed. The 6-40 thread makes it appropriate for miniature hardware applications, instrument panels, small fixtures, and light industrial tooling. The nylon ball reduces marring on soft or finished surfaces, making it a practical choice where contact damage to the mating part must be avoided. It is sold individually and suited for both original equipment builds and maintenance replacement.

Key Features

• 6-40 thread size for use in miniature and precision threaded bores
• Nylon ball construction minimizes surface marring on contact surfaces
• Zinc-plated steel body provides corrosion resistance in general-purpose environments
• 0.023 inch maximum ball reach for controlled, low-profile detent engagement
• 0.5 pound initial end force and 1 pound final end force for repeatable light-duty positioning
• No locking element — threads directly into tapped hole without secondary retention hardware

Compatibility

Designed as a direct-fit threaded ball plunger for applications requiring a 6-40 threaded detent component in light mechanical assemblies, fixtures, and instrumentation.

Installation Notes

Install using a driver or wrench sized for the 6-40 thread form — take care not to overtighten, as the small thread size is susceptible to stripping. Ensure the mating bore is clean and properly tapped to 6-40 before installation. No power shutoff is required for purely mechanical applications, but de-energize any associated equipment before servicing assemblies that incorporate electrical or pneumatic systems. Verify ball movement is free and unobstructed after installation.
