Gibraltar SWN10-8-PT-G Threaded Spring Plunger 1/2-13

Product Description

The GIBRALTAR SWN10-8-PT-G is a threaded spring plunger designed to provide controlled, repeatable positioning force in mechanical assemblies and fixtures. The plunger features a 1/2-13 thread with a 1-1/4 inch thread length and delivers an initial end force of 6.6 pounds and a final end force of 17.4 pounds. The steel body provides structural rigidity while the nylon nose reduces surface marking and wear on mating components. A built-in locking element secures the plunger body after installation, preventing back-out under vibration. This part is typically installed by machinists, toolmakers, and mechanical assembly technicians working with jigs, fixtures, and positioning components.

This spring plunger is suited for use in standard tooling and fixture applications where a positive, spring-loaded detent or positioning stop is required. The 1/4 inch plunger projection provides consistent engagement depth. The 1/2-13 thread size is a common inch-series thread found in steel tooling plates and fixture blocks across light industrial and manufacturing environments. It is sold individually and is appropriate for both OEM assembly builds and maintenance replacement situations.

Key Features

• 1/2-13 thread with 1-1/4 inch thread length for standard tooling plate installation
• 6.6 pound initial end force and 17.4 pound final end force for controlled detent resistance
• 1/4 inch plunger projection for consistent engagement depth
• Steel body construction for durability in industrial fixture applications
• Nylon nose reduces marking and wear on contact surfaces
• Integrated locking element prevents back-out under vibration

Compatibility

Designed as a standard inch-series threaded spring plunger for use in tooling plates, jigs, and mechanical fixtures that accept a 1/2-13 threaded hole.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using a hex key or spanner wrench suited to the plunger body. Ensure the receiving threaded hole is clean and properly tapped to 1/2-13 before installation. The locking element should be engaged after the plunger is threaded to the correct depth to prevent loosening during operation. De-energize or lock out any equipment before installing or servicing spring plungers in active assemblies.
