Gibraltar SWN10-4AFS-G Threaded Spring Plunger 1/4-20

Product Description

The GIBRALTAR SWN10-4AFS-G is a short-style threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The steel body accepts a 1/4-20 thread and offers a 5/8-inch thread length for secure installation into tapped holes. The Delrin nose provides a smooth, low-friction contact surface. Initial end force is 0.30 pounds, and final end force is 3.50 pounds, making it well suited for applications that require consistent, repeatable spring-loaded engagement without a locking element.

This spring plunger is used in general industrial, mechanical, and precision assembly settings where controlled plunger projection and reliable spring return are required. The short plunger length and 3/16-inch projection suit confined or space-restricted mounting locations. Typical installations include fixtures, tooling plates, jigs, and panel assemblies. No locking element is present, so the plunger threads freely into the tapped hole for straightforward installation and removal.

Key Features

• Steel body construction for durability in industrial service
• Delrin nose for low-friction, non-marring contact
• 1/4-20 thread size with 5/8-inch thread length for standard tapped-hole fitment
• Short plunger length with 3/16-inch projection for space-restricted assemblies
• 0.30 lb initial end force and 3.50 lb final end force for consistent spring-loaded engagement
• No locking element for easy, tool-free thread adjustment

Compatibility

Designed for use in any tapped 1/4-20 hole requiring a short-style threaded spring plunger with a non-locking steel body and Delrin nose.

Installation Notes

Thread the plunger into a clean, properly tapped 1/4-20 hole using a hex key or spanner wrench on the body flats. Ensure the mating assembly is depowered or de-energized before installation when working in automated or powered fixtures. Do not overtighten, as excessive torque can deform the body or damage the thread. Verify plunger projection and spring force alignment with the application requirements before final assembly.
