Gibraltar SSWN10-5B-G Threaded Ball Plunger 5/16-18

Product Description

The GIBRALTAR SSWN10-5B-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in industrial and mechanical assemblies. It features a stainless steel body with a nylon ball and a 5/16-18 thread for straightforward installation into tapped holes. The body measures 0.578 inches in length with a ball diameter of 0.156 inches and a maximum ball reach of 0.04 inches. Initial end force is 4 pounds, and final end force is 9 pounds, giving the plunger a defined spring-load range suited to repeatable positioning tasks. Machinists, toolmakers, and maintenance technicians commonly install this type of component.

This ball plunger is used in fixtures, jigs, machine tooling, and light mechanical assemblies where a spring-loaded ball is needed to hold a part in position or provide tactile detent feedback. The nylon ball is appropriate for applications where a softer contact surface is preferred to avoid marring mating parts. The 5/16-18 thread allows installation in standard tapped holes found across a wide range of metal and plastic assemblies in both production and maintenance environments.

Key Features

• Stainless steel body provides corrosion resistance in demanding shop environments
• Nylon ball offers soft contact to protect mating surfaces from scratching or galling
• 5/16-18 thread fits standard tapped holes for straightforward installation
• 4-pound initial end force and 9-pound final end force deliver consistent spring-load detent action
• Compact body length of 0.578 inches suits space-constrained fixture and tooling applications
• No locking element — torque into place and adjust position as needed during setup

Compatibility

Designed as a standard threaded ball plunger for use in any tapped 5/16-18 hole in fixtures, jigs, machine tooling, or general mechanical assemblies requiring a spring-loaded positioning element.

Installation Notes

Installation requires a tapped 5/16-18 hole in the mating component. Use a wrench on the body hex or a screwdriver slot if present, and thread in by hand before applying tool torque. Ensure the assembly is de-energized and any moving machinery is locked out before installing or adjusting plungers in live equipment. Do not over-torque, as this can distort the body and affect ball travel and spring force.
