Gibraltar SW10-10A-PT-G Threaded Spring Plunger 5/8-11

Product Description

The GIBRALTAR SW10-10A-PT-G is a standard threaded spring plunger designed for indexing, positioning, and light-duty detent applications in industrial and mechanical assemblies. The body and nose are both steel construction, providing durability in demanding service environments. It carries a 5/8-11 thread with a 1-1/2 inch thread length and a maximum plunger diameter of 0.31 inches. The plunger projection measures 5/16 inches, with an initial end force of 3.5 pounds and a final end force of 10.5 pounds. A locking element is included to secure the plunger in position once installed. This component is typically installed by machinists, toolmakers, or maintenance technicians working on fixtures, jigs, and precision assemblies.

This spring plunger is suited for use in machine fixtures, workholding devices, tooling plates, and mechanical housings where repeatable positioning or controlled detent resistance is required. It threads directly into a tapped hole and provides consistent spring force to locate or hold components in place. The locking element prevents the plunger from backing out under vibration or repeated cycling, making it appropriate for both static and dynamic load applications in light manufacturing and assembly environments.

Key Features

• 5/8-11 thread size with 1-1/2 inch thread length for secure installation in tapped holes
• Steel body and nose construction for wear resistance and long service life
• Standard plunger projection of 5/16 inches (0.3125 inches decimal)
• Initial end force of 3.5 pounds and final end force of 10.5 pounds for predictable detent performance
• Integrated locking element prevents backing out under vibration or cyclic loading
• Maximum plunger diameter of 0.31 inches for precise fitment in standard bores

Compatibility

Designed as a direct-thread replacement or new-installation spring plunger for tapped holes sized to 5/8-11 thread in industrial fixtures, jigs, tooling plates, and mechanical housings requiring standard-projection detent or positioning function.

Installation Notes

Installation is performed by threading the plunger into a properly tapped 5/8-11 hole using the appropriate wrench or spanner on the body flats. Ensure the mating hole is clean and free of chips or debris before installation. Engage the locking element per standard practice to prevent rotation or backing out during service. De-energize or lock out any machine or fixture before servicing or replacing spring plungers in a live assembly.
