Gibraltar SWN10-10FS-PT-G Threaded Spring Plunger 5/8-11

Product Description

The GIBRALTAR SWN10-10FS-PT-G is a short-type threaded spring plunger designed for indexing, positioning, and light-duty holding applications in industrial and mechanical assemblies. The body is machined from steel with a Delrin nose, combining corrosion resistance at the contact point with structural rigidity in the body. The plunger delivers an initial end force of 3.5 pounds and a final end force of 26 pounds, making it suitable for applications that require a positive detent feel without excessive actuation force. A locking element is included to secure the plunger in position after installation. Machinists, tool and die professionals, and maintenance technicians install this type of component in fixtures, jigs, and equipment panels.

This spring plunger fits applications requiring a 5/8-11 threaded hole with a thread engagement length of 1-1/8 inches. The maximum plunger diameter is 0.31 inches and the projection is 5/16 inches, placing it in the short-projection category. It is commonly used in production fixtures, tooling plates, machine housings, and equipment enclosures where repeatable positioning or panel retention is needed. The steel body construction makes it appropriate for industrial environments with moderate mechanical loading.

Key Features

• 5/8-11 thread size with 1-1/8 inch thread length for secure engagement
• Steel body provides structural rigidity under mechanical load
• Delrin nose reduces friction and wear at the contact surface
• Initial end force of 3.5 pounds and final end force of 26 pounds for positive detent feel
• Short plunger projection of 5/16 inches suits low-clearance installations
• Locking element included to prevent back-out after installation

Compatibility

Designed as a standard threaded spring plunger for use in any application requiring a 5/8-11 threaded bore, suitable for industrial fixtures, jigs, tooling plates, and mechanical assemblies where short-projection indexing or detent retention is required.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 5/8-11 hole using a spanner wrench or appropriate tool interfacing with the hex or slot features on the body. Ensure the mating thread is clean and free of debris before installation. Engage the locking element per the manufacturer procedure to prevent the plunger from backing out under vibration. De-energize or secure any moving equipment before servicing fixtures or assemblies that contain spring plungers.
