Gibraltar SWN10-6FS-PT-G Threaded Spring Plunger 3/8-16

Product Description

The GIBRALTAR SWN10-6FS-PT-G is a short-body threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The steel body houses a Delrin nose and an integrated locking element that secures the plunger in the threaded bore once installed. It delivers an initial end force of 1 pound and a final end force of 12 pounds, making it suitable for applications where controlled, repeatable spring pressure is required. Machinists, toolmakers, and mechanical assembly technicians install this type of component in jigs, fixtures, slides, and similar precision mechanisms.

This spring plunger is used in industrial and mechanical assembly environments where a threaded, spring-loaded positioning element is needed in a compact form factor. The short plunger length type suits installations with limited depth clearance. Its 3/8-16 thread size is a common unified coarse thread, compatible with standard tapped holes in steel, aluminum, and similar materials found in fixture and tooling applications.

Key Features

• Steel body construction for durability in industrial service
• Delrin nose material reduces friction and wear on mating surfaces
• Integrated locking element secures plunger position after installation
• 1 pound initial end force and 12 pound final end force for controlled spring pressure
• Short plunger length type for use in confined or shallow-bore applications
• 3/8-16 unified coarse thread with 11/16 inch thread length for positive engagement

Compatibility

Designed as a direct-fit threaded spring plunger for standard 3/8-16 tapped holes in jigs, fixtures, slides, and mechanical positioning assemblies requiring a short-body, locking-style plunger.

Installation Notes

Installation is performed by toolmakers or mechanical assembly technicians using a standard hex wrench or spanner tool appropriate for the plunger head style. The receiving bore must be tapped to 3/8-16 and cleaned of chips or debris before threading the plunger in. Torque to snug engagement without overdriving, as over-tightening can damage the locking element or deform the body. De-energize or lock out any associated moving machinery before servicing plungers in active fixtures.
