Gibraltar SSWN10-5BH-PT-G Threaded Ball Plunger 5/16-18

Product Description

The GIBRALTAR SSWN10-5BH-PT-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The body is machined from stainless steel and uses a nylon ball, making it well-suited for corrosion-sensitive environments or applications where the ball must make contact with softer mating surfaces without marking them. Thread size is 5/16-18, body length is 0.578 inches, and ball diameter is 0.156 inches. Initial end force is 6 pounds and final end force is 17 pounds. A locking element is integrated into the body to secure the plunger once installed. Machinists, toolmakers, and maintenance technicians are the typical installers.

This ball plunger is used in jigs, fixtures, machine tool components, and positioning mechanisms where repeatable detent action is needed. The 5/16-18 thread allows installation into standard tapped holes in steel, aluminum, or plastic assemblies. The stainless steel body resists corrosion in wash-down or high-humidity environments, while the nylon ball provides low-friction contact without damaging delicate mating surfaces. Maximum ball reach is 0.04 inches, making this plunger suitable for shallow engagement applications.

Key Features

• Stainless steel body for corrosion resistance in harsh or wash-down environments
• Nylon ball provides low-friction, non-marring contact with mating surfaces
• 5/16-18 thread fits standard tapped holes for straightforward installation
• Integrated locking element prevents loosening under vibration or repeated cycling
• 6-pound initial end force and 17-pound final end force for consistent detent engagement
• Compact 0.578-inch body length suits space-constrained assemblies

Compatibility

Designed as a direct-install threaded ball plunger for any mechanical assembly or fixture with a standard 5/16-18 tapped hole requiring a detent or positioning function.

Installation Notes

Installation requires a standard 5/16-18 tapped hole in the receiving component. Use the integrated locking element to secure the plunger at the desired depth before finalizing position. Ensure the mating surface travel aligns with the ball reach of 0.04 inches to achieve proper detent action. Degrease threads before installation if adhesive thread-locking compounds are to be used in place of or in addition to the mechanical locking element.
