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

Product Description

The GIBRALTAR SWN10-8-G is a threaded spring plunger designed for indexing, positioning, and light-duty holding applications in mechanical assemblies. The steel body accepts a 1/2-13 thread and offers a 1-1/4 inch thread length with a 1/4 inch plunger projection. The nylon nose delivers an initial end force of 6.6 pounds and a final end force of 17.4 pounds, making it suitable for repeatable, low-impact locating tasks. Machinists, tool-and-die technicians, and mechanical assemblers install this type of component in fixtures, jigs, and production tooling where controlled spring tension is required.

This spring plunger fits into threaded bores in metal or plastic workholding fixtures, machine frames, and assembly jigs. It is commonly used in production environments where a component must be repeatedly seated and released without tooling damage. The nylon nose protects mating surfaces from scoring during contact. The standard plunger length type suits the majority of general-purpose fixture and tooling applications.

Key Features

• 1/2-13 thread size with 1-1/4 inch thread length for secure installation in standard tapped bores
• 1/4 inch plunger projection provides controlled engagement depth
• 6.6 lb initial end force and 17.4 lb final end force for consistent spring-loaded positioning
• Steel body construction for durability in industrial tooling environments
• Nylon nose protects mating surfaces from wear and scoring
• No locking element — allows straightforward installation and removal without staking or thread-locking

Compatibility

Designed as a standard OEM-style threaded spring plunger for use in machined fixtures, jigs, and mechanical assemblies requiring a 1/2-13 tapped bore.

Installation Notes

Installation is performed by machinists or mechanical assemblers using a hex key or spanner wrench suited to the body style. Ensure the mating bore is clean and threads are chased before installation to prevent galling. Verify that the bore depth accommodates the 1-1/4 inch body length and that the 1/4 inch projection clears surrounding geometry under full compression. No power source or fluid system shutoff is required for this mechanical fastener component.
