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

Product Description

The GIBRALTAR SWN10-6AFS-G is a short-pattern threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The body is made from steel, with a Delrin nose that reduces friction and resists wear against mating surfaces. The plunger carries a 3/8-16 thread and an 11/16-inch thread length, with a maximum plunger diameter of 0.186 inches and a 3/16-inch projection. Initial end force is 1.5 pounds and final end force is 7.5 pounds, making it suitable for applications requiring consistent, repeatable spring tension without a locking element.

This spring plunger is used in fixtures, jigs, machine tooling, and light mechanical assemblies where a threaded body is needed to retain or position a component under spring load. The short plunger length suits tight clearance installations. No locking element is included, so the plunger can be adjusted or removed by threading it in or out of the tapped hole. Typical installation environments include production machinery, assembly fixtures, and industrial equipment requiring a small-diameter spring-loaded locating point.

Key Features

• 3/8-16 thread size with 11/16-inch thread length for secure engagement in tapped holes
• Steel body construction for durability in industrial and mechanical applications
• Delrin nose minimizes friction and wear against contact surfaces
• 1.5-pound initial end force and 7.5-pound final end force for consistent spring-loaded positioning
• Short plunger length suits tight-clearance and low-profile installations
• No locking element allows straightforward adjustment and removal

Compatibility

Designed as a standard threaded spring plunger for use in any tapped hole accepting a 3/8-16 thread, suitable for common fixturing, tooling, and light mechanical positioning applications.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped 3/8-16 hole using a hex key or appropriate wrench on the plunger body flats. De-energize or lock out any machinery before installing or adjusting spring plungers in active assemblies. Do not overtighten, as this can compress the spring beyond its rated travel and reduce service life. A thread-locking compound may be applied if vibration could cause the plunger to back out during operation.
