Gibraltar SW10-6SL-G Threaded Spring Plunger 3/8-16

Product Description

The GIBRALTAR SW10-6SL-G is a stubby threaded spring plunger designed to provide controlled, repeatable end force in positioning, indexing, and workholding applications. The steel body features a 3/8-16 thread with a 5/8-inch thread length and a maximum plunger diameter of 0.186 inches. The plunger projection measures 0.11 inches. Initial end force is 1.5 pounds, with a final end force of 5 pounds. This type of plunger is installed by machinists, toolmakers, and mechanical assembly technicians working with fixtures, jigs, and precision equipment.

The SW10-6SL-G fits applications where a compact, low-profile stubby plunger is required. Its 3/8-16 thread makes it compatible with standard tapped holes in steel or aluminum fixture plates. Typical use cases include part location in assembly fixtures, detent positioning on sliding mechanisms, and spring-loaded contact points in industrial tooling. The unit ships individually and is suited for low-volume repair or replacement as well as single-position fixture builds.

Key Features

• 3/8-16 thread size with 5/8-inch thread length for standard fixture-plate installation
• Stubby plunger profile with 0.11-inch projection for space-constrained applications
• 1.5-pound initial end force and 5-pound final end force for light-duty indexing and positioning
• Steel body and steel nose for durability in industrial environments
• No locking element, allowing free spring action without thread-lock interference

Compatibility

Designed as a direct-fit replacement or new-installation threaded spring plunger for tapped 3/8-16 holes in fixture plates, jigs, and mechanical assemblies requiring a stubby plunger profile.

Installation Notes

Installation is performed by hand or with a hex key or open-end wrench into a pre-tapped 3/8-16 hole. Ensure the mating hole is clean and free of debris before threading the plunger in. Do not overtighten, as this can bind the internal spring and reduce plunger travel. No special tools or certifications are required for standard fixture-plate installation.
