Gibraltar SSWN10-5SL-G Threaded Spring Plunger 5/16-18

Product Description

The GIBRALTAR SSWN10-5SL-G is a stubby threaded spring plunger designed to provide controlled, spring-loaded positioning and indexing force in mechanical assemblies. The body is constructed from stainless steel with a nylon nose, offering corrosion resistance and low-friction contact at the plunger tip. It features a 5/16-18 thread with a 0.562 inch thread length and a maximum plunger diameter of 0.135 inches. Initial end force is 1.25 pounds, and final end force is 4 pounds. This part is installed by machinists, maintenance technicians, and mechanical assemblers working on jigs, fixtures, tooling, and precision equipment.

This spring plunger is suited for light-duty positioning, detenting, and locating applications in industrial and mechanical settings. The stubby plunger length type makes it appropriate for installations where axial space is limited. The nylon nose reduces marking or damage to workpiece surfaces on contact. It is typically installed into threaded bores in tooling plates, fixture bodies, machine frames, and assembly jigs requiring repeatable tactile or mechanical detent action.

Key Features

• 5/16-18 thread size with 0.562 inch thread and body length for compact installation
• Stainless steel body for corrosion resistance in washdown or humid environments
• Nylon nose minimizes surface marking on contacted workpieces
• Stubby plunger profile suits space-constrained mounting locations
• 1.25 pounds initial end force and 4 pounds final end force for light-duty detent applications
• No locking element — threads directly into tapped hole without secondary retention hardware

Compatibility

Designed as a direct-install threaded spring plunger for any application with a standard 5/16-18 tapped bore requiring a stubby-profile, stainless steel body plunger with a nylon nose.

Installation Notes

Installation requires a properly tapped 5/16-18 threaded bore in the mating component. Use an appropriate hex key or slotted driver to thread the plunger in by hand until snug — do not overtorque, as stainless steel fasteners are susceptible to galling. Ensure the plunger axis is aligned with the direction of detent travel before final seating. De-energize or lock out any moving machinery before installing or adjusting spring plungers in active assemblies.
