Gibraltar SWN10-8S-G Threaded Spring Plunger 1/2-13

Product Description

The GIBRALTAR SWN10-8S-G is a stubby threaded spring plunger designed for indexing, positioning, and locking applications in industrial and mechanical assemblies. It features a 1/2-13 thread with a 0.75 inch thread length and a maximum plunger diameter of 0.248 inches. The plunger projection measures 0.151 inches. With an initial end force of 5 pounds and a final end force of 28.5 pounds, this plunger delivers reliable spring-loaded engagement across a range of clamping and detent applications. Both the body and nose are constructed from steel for durability in demanding service environments. Licensed mechanical technicians and assembly professionals handle installation in production, tooling, and machine-building contexts.

This spring plunger is suited for use in jigs, fixtures, machine tools, and automated assembly equipment where repeatable part positioning or light-duty locking is required. The stubby body profile makes it well suited for installations where axial space is limited. It is sold individually and is appropriate for both OEM production builds and maintenance replacement applications in general industrial environments.

Key Features

• 1/2-13 thread size with 0.75 inch thread length for secure installation in standard tapped holes
• Stubby body length of 0.75 inches suits space-constrained mounting locations
• Steel body and steel nose construction for durability in industrial service
• 5 pound initial end force and 28.5 pound final end force for reliable spring-loaded detent action
• Maximum plunger diameter of 0.248 inches
• No locking element — installs and adjusts without thread-locking inserts

Compatibility

Designed as a standard threaded spring plunger replacement or new installation component for industrial jigs, fixtures, machine tools, and assembly equipment using 1/2-13 tapped holes.

Installation Notes

Installation is performed by mechanical technicians or toolmakers using standard hand tools. Ensure the mating tapped hole is clean and free of debris before threading the plunger in. De-energize or lock out any moving machinery before servicing spring plungers in automated equipment. Do not overtighten, as this can compress the spring beyond its operating range and reduce plunger function.
