Gibraltar SW10-4X-G Threaded Spring Plunger 1/4-20

Product Description

The GIBRALTAR SW10-4X-G is a threaded spring plunger designed for use in indexing, positioning, and light-duty holding applications across industrial and mechanical assemblies. The plunger features a 1/4-20 thread with a 3/4 inch thread length and a maximum plunger diameter of 0.118 inches. Initial end force is 2 pounds and final end force is 9 pounds, making it suitable for applications requiring consistent, repeatable spring tension without a locking element. Both the body and nose are constructed from steel for durability in production and maintenance environments. This type of component is typically installed by machinists, maintenance technicians, or mechanical assemblers.

The SW10-4X-G is used in jigs, fixtures, tooling plates, and mechanical assemblies where a spring-loaded plunger is needed to locate, stop, or lightly retain a sliding or rotating component. The standard plunger length type and 1/8 inch projection make it appropriate for low-clearance installations where minimal nose extension is required. It is sold individually and suits both OEM production runs and MRO replacement scenarios in light manufacturing and industrial maintenance settings.

Key Features

• 1/4-20 thread with 3/4 inch thread length for standard threaded hole installation
• Steel body and steel nose for durability in industrial environments
• 2 pound initial end force and 9 pound final end force for controlled spring engagement
• Maximum plunger diameter of 0.118 inches with 0.125 inch (1/8 inch) projection
• No locking element — installs and removes with standard tooling
• Standard plunger length type suitable for low-clearance fixture and tooling applications

Compatibility

Designed as a standard threaded spring plunger for use in any threaded hole accepting a 1/4-20 fastener, including jigs, fixtures, tooling plates, and general mechanical assemblies requiring spring-loaded positioning or light retention.

Installation Notes

Installation is performed by threading the plunger body into a prepared 1/4-20 tapped hole using a hex key or wrench sized to the body flats. Ensure the mating threaded hole is clean and free of debris before installation to avoid thread damage. No power source is required, but technicians should verify plunger projection clearance against the mating surface before final torque. Follow applicable facility or equipment maintenance procedures when servicing assemblies that contain these components.
