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

Product Description

The GIBRALTAR SWN10-8AFS-G is a threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The steel body houses a Delrin nose that delivers smooth, low-friction contact against mating surfaces. It installs into a standard 1/2-13 tapped hole and provides a 1/4-inch plunger projection at full engagement. With an initial end force of 1.70 pounds and a final end force of 8.50 pounds, it delivers consistent spring tension across the travel range. Machinists, toolmakers, and maintenance technicians working with jigs, fixtures, and machine components are the primary installers.

This short-style spring plunger is suited for use in jigs, fixtures, machine tool components, and fabricated assemblies where a threaded, spring-loaded positioning element is required. The 1/2-13 thread size makes it compatible with standard tapped holes found in steel and aluminum workpieces across general manufacturing and industrial maintenance environments. No locking element is present, making it straightforward to install and remove by hand or with common hand tools.

Key Features

• Steel body construction for durability in industrial and machine-shop environments
• Delrin nose material provides low-friction, non-marring contact with mating surfaces
• 1/2-13 thread size fits standard tapped holes in steel and aluminum workpieces
• Short plunger length type with 1/4-inch projection for compact assembly clearances
• 1.70-pound initial end force and 8.50-pound final end force for consistent spring-loaded positioning
• No locking element — simple installation and removal with standard hand tools

Compatibility

Designed as an OEM-style replacement or new-install spring plunger for any assembly requiring a 1/2-13 threaded short-style spring plunger with a 0.248-inch maximum plunger diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard hex wrench or spanner. The mating tapped hole must be clean and free of debris before threading in the plunger. De-energize or lock out any machine before servicing components that contain spring plungers. Do not overtighten, as doing so can compress the internal spring beyond its design range and reduce end force accuracy.
