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

Product Description

The GIBRALTAR SW10-4XFS-G is a short-body threaded spring plunger designed for use in fixturing, jigs, tooling, and mechanical assemblies where controlled spring-loaded positioning or detenting is required. The plunger features a 1/4-20 thread size with a 5/8-inch thread length, a maximum plunger diameter of 0.119 inches, and a 3/16-inch projection. Initial end force is 0.5 pounds and final end force is 6 pounds. Both the body and nose are constructed from steel, providing durability in demanding shop and industrial environments. This type of component is installed by machinists, toolmakers, and maintenance technicians.

This spring plunger is suited for applications requiring repeatable positioning, light-duty locking, or spring-loaded detent action in metal fixtures, machine tooling, and mechanical assemblies. The short plunger length type makes it appropriate for space-constrained installations where a lower-profile plunger is needed. It threads directly into a tapped hole, requiring no locking element, and is commonly used in production fixtures, jig plates, and assembly tooling across general manufacturing and maintenance environments.

Key Features

• 1/4-20 thread size with 5/8-inch thread length for direct installation into standard tapped holes
• 0.119-inch maximum plunger diameter with 3/16-inch projection
• 0.5-pound initial end force and 6-pound final end force for light-duty spring-loaded detent action
• Steel body and steel nose for durability in industrial and shop environments
• Short plunger length type suited for low-profile and space-constrained installations
• No locking element — installs and adjusts with standard hex or spanner tools

Compatibility

Designed as a standard threaded spring plunger for use in any application accepting a 1/4-20 threaded hole requiring a short-body, steel-nose detent or positioning plunger.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 1/4-20 hole using the appropriate tool for the drive style on the plunger head. Ensure the receiving bore and mating surfaces are clean and free of debris before installation. Do not overtighten, as this can compress the internal spring beyond its rated travel and reduce service life. No locking element is included, so thread-locking compound may be applied at the installer's discretion if vibration resistance is required.
