Gibraltar SWN10-8B-G Threaded Ball Plunger 1/2-13

Product Description

The GIBRALTAR SWN10-8B-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 1/2-13 threaded steel body with a zinc-plated finish and a nylon ball that provides smooth, low-friction contact against mating surfaces. The ball diameter measures 0.281 inches with a maximum ball reach of 0.072 inches. Initial end force is 6 pounds and final end force is 12 pounds, making this unit suitable for applications requiring a consistent, repeatable hold force. Machinists, toolmakers, and maintenance technicians commonly install these in jigs, fixtures, and production tooling.

This ball plunger is used in industrial and manufacturing environments where controlled positioning or light retention is needed. It threads directly into a tapped hole and requires no additional hardware. Typical applications include fixture stops, panel latches, drawer detents, and alignment points on machine components. The nylon ball minimizes surface marring on softer contact materials, making it a practical choice where metal-on-metal contact is undesirable.

Key Features

• 1/2-13 threaded body for direct installation into standard tapped holes
• Nylon ball resists corrosion and reduces surface marking on contact parts
• Steel body with zinc-plated finish for corrosion resistance in shop environments
• 6-pound initial end force and 12-pound final end force for consistent detent action
• Compact 0.75-inch body length suits tight clearance applications
• No locking element required — threads in and seats without secondary fasteners

Compatibility

Designed as a standard 1/2-13 threaded ball plunger for use in any tapped hole meeting that thread specification, across jigs, fixtures, tooling plates, and general industrial assemblies.

Installation Notes

Installation requires a correctly tapped 1/2-13 hole in the mating component. De-energize or lock out any machinery before servicing assemblies that contain this plunger. Use an appropriate wrench on the hex body to avoid damaging the ball or bore during installation. Do not over-torque, as this can distort the body bore and impair ball travel.
