Gibraltar SWN10-5A-PT-G Threaded Spring Plunger 5/16-18

Product Description

The GIBRALTAR SWN10-5A-PT-G is a threaded spring plunger designed for indexing, positioning, and locating applications in industrial and mechanical assemblies. It features a 5/16-18 thread size with a 1 inch thread length and a steel body for durability under repeated cycling. The nylon nose protects mating surfaces from damage during contact. Initial end force is 1.5 pounds and final end force is 4.5 pounds, making it suitable for light-duty holding and detent applications. A built-in locking element secures the plunger in the threaded bore without the need for separate hardware. Machinists, tool and die technicians, and mechanical assemblers typically install this component.

The SWN10-5A-PT-G is used in fixtures, jigs, machine tools, and production equipment where controlled spring force is needed to hold a position or provide tactile detent feedback. The standard plunger length type and 0.135 inch maximum plunger diameter make it a common fit for compact assemblies where space is limited. The 3/16 inch projection provides consistent engagement depth across repeated cycles. This plunger is suited to both light manufacturing environments and precision fixture builds.

Key Features

• 5/16-18 thread size with 1 inch thread length for secure installation in standard tapped bores
• Steel body construction for durability in industrial environments
• Nylon nose protects contact surfaces from wear and marring
• Built-in locking element eliminates the need for thread-locking compounds or jam nuts
• 1.5 pound initial end force and 4.5 pound final end force for light-duty detent and positioning use
• 3/16 inch plunger projection provides consistent and repeatable engagement

Compatibility

Designed as a standard-style threaded spring plunger for use in any machined or tapped 5/16-18 bore where a spring-loaded positioning or detent function is required.

Installation Notes

Installation requires a properly tapped 5/16-18 through or blind hole. Thread the plunger in by hand initially, then use an appropriate wrench or spanner to seat it to the desired depth. Ensure the bore is clean and free of chips or debris before installation. The locking element engages the bore threads to resist backing out under vibration, so no additional thread locker is required.
