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

Product Description

The GIBRALTAR SW10-4SL-G is a stubby threaded spring plunger designed to provide controlled, spring-loaded contact force in mechanical assemblies. The steel body threads into a tapped hole using a standard 1/4-20 thread, with a thread length of 0.531 inches and a maximum plunger diameter of 0.119 inches. The plunger nose projects 0.078 inches beyond the body face, delivering an initial end force of 1 pound and a final end force of 3.5 pounds. Machinists, tool and die technicians, and mechanical assembly professionals install this type of component in fixtures, jigs, and positioning mechanisms where repeatable, spring-loaded indexing or detent action is required.

This spring plunger is suited for use in light-duty mechanical assemblies where precise, low-force plunger action is needed. The stubby body length keeps the installed profile compact, making it a practical choice for applications with limited depth clearance. Typical uses include workholding fixtures, alignment jigs, drawer stops, and light detent mechanisms in both industrial and trade-shop environments. The steel nose and body construction offer durability in moderate-duty applications.

Key Features

• Standard 1/4-20 thread for easy installation into pre-tapped holes
• Stubby body profile at 0.531 inches body length suits shallow-depth applications
• 1 pound initial end force and 3.5 pounds final end force for controlled spring tension
• Steel body and steel nose material for durability in mechanical assemblies
• 0.078 inches plunger projection provides positive contact without excessive travel
• No locking element — threads in with standard hex or slotted tooling

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical fixtures and assemblies requiring a 1/4-20 threaded spring plunger with a stubby body profile.

Installation Notes

Install into a properly tapped 1/4-20 through or blind hole using appropriate hand tools. Ensure the receiving hole depth accommodates the 0.531 inches thread length without bottoming out the plunger body prematurely. De-energize or lock out any machinery before servicing fixtures or assemblies that contain spring plungers. Do not overtighten, as excessive torque can deform the body or restrict plunger movement.
