Gibraltar SW10-8FS-G Threaded Spring Plunger 1/2-13 Steel

Product Description

The GIBRALTAR SW10-8FS-G is a threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The plunger features a 1/2-13 thread size with a thread length of 13/16 inches and a maximum plunger diameter of 0.248 inches. Projection from the nose is 1/4 inch. The steel body and steel nose deliver durability in industrial and machine-shop environments. Initial end force is 2.5 pounds and final end force is 15 pounds. This short plunger-length-type component is installed by machinists, maintenance technicians, and mechanical assemblers working with jigs, fixtures, or tooling systems.

This spring plunger is suited for use in machine fixtures, assembly jigs, tooling plates, and mechanical indexing applications where repeatable positioning or light detent action is required. The 1/2-13 thread makes it compatible with standard tapped holes commonly found in steel and aluminum tooling components. It is typically used in industrial manufacturing, MRO maintenance, and precision assembly environments. No locking element is present, so the plunger threads directly into the mating hole without thread-locking features.

Key Features

• 1/2-13 thread size with 13/16 inch thread length for standard tapped-hole installation
• 1/4 inch plunger projection for consistent detent or positioning travel
• 2.5 pound initial end force and 15 pound final end force for reliable spring tension
• Steel body and steel nose construction for durability in industrial environments
• Short plunger length type suited for space-constrained fixture applications
• No locking element — installs and adjusts with standard hex or spanner tooling

Compatibility

Designed for installation into standard 1/2-13 tapped holes in steel, aluminum, or other materials used in industrial fixtures, jigs, and tooling plates.

Installation Notes

Installation is performed by machinists or mechanical technicians using standard hand tools compatible with the thread drive style. Ensure the mating tapped hole is clean and properly sized for 1/2-13 threads before installation. De-energize or lock out any associated machinery before servicing or replacing spring plungers in active fixtures. Do not overtighten, as excessive torque can damage the plunger body or compress the internal spring beyond its design range.
