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

Product Description

The GIBRALTAR SW10-6SL-PT-G is a stubby threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The plunger features a 3/8-16 thread with a 0.625 inches thread length and a 0.186 inches maximum plunger diameter, delivering a 0.11 inches nose projection. Initial end force is 1.5 pounds and final end force is 5 pounds, making it well suited for applications requiring positive, repeatable positioning with controlled spring resistance. The steel body and steel nose construction provide durability in typical shop and industrial environments. A built-in locking element secures the plunger in position, preventing backing out under vibration or repeated cycling. Installed by machinists, toolmakers, and mechanical assemblers.

This spring plunger is used in jigs, fixtures, tooling plates, machine slides, and similar precision assemblies where a compact, stubby form factor is required. The 3/8-16 thread allows installation into standard tapped holes in steel or aluminum plates. The locking element engages the threaded bore to hold the plunger at a set depth without the need for a separate jam nut. Typical applications include part-locating fixtures, detent mechanisms, and spring-loaded retention features in light to medium-duty mechanical assemblies.

Key Features

• 3/8-16 thread with 0.625 inches thread length for installation in standard tapped holes
• 0.186 inches maximum plunger diameter with 0.11 inches nose projection
• 1.5 pounds initial end force and 5 pounds final end force for controlled spring resistance
• Steel body and steel nose for durability in industrial and tooling environments
• Integrated locking element secures plunger depth without a jam nut

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies, jigs, fixtures, and tooling plates that accept a 3/8-16 threaded spring plunger with a stubby body profile.

Installation Notes

Installation requires a properly tapped 3/8-16 hole to the appropriate depth. Use a hex key or spanner wrench to thread the plunger into the bore and engage the locking element at the desired depth. De-energize or lock out any powered equipment before servicing assemblies containing spring plungers. Avoid over-tightening, as this can damage the locking element or distort the plunger body.
