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

Product Description

The GIBRALTAR SWN10-8S-PT-G is a threaded spring plunger designed for use in positioning, indexing, and light-duty locking applications across industrial and mechanical assemblies. The plunger features a 1/2-13 thread size with a 3/4-inch thread length and a stubby plunger configuration. The steel body provides structural durability, while the nylon nose reduces surface marking on mating components. An integrated locking element secures the plunger in place after installation, preventing rotation under vibration or repeated loading. Initial end force is 5 pounds, with a final end force of 28.5 pounds, making it suitable for moderate-force indexing and detent applications.

This spring plunger is used in machine fixtures, jigs, tooling plates, and mechanical assemblies where repeatable positioning or controlled detent force is required. The 1/2-13 thread fits standard tapped holes and is commonly installed in steel or aluminum housings. The stubby plunger body suits confined spaces where a standard-length plunger would interfere with adjacent components. Machinists, tool-and-die technicians, and mechanical assembly professionals install this type of hardware in production and maintenance environments.

Key Features

• 1/2-13 thread size with 3/4-inch thread length for standard tapped-hole installation
• Stubby plunger profile suited for space-constrained assemblies
• Steel body construction for durability in industrial environments
• Nylon nose protects mating surfaces from scoring or marking
• Integrated locking element prevents rotation after installation
• 5-pound initial end force and 28.5-pound final end force for controlled detent action

Compatibility

Designed as a standard threaded spring plunger for use in fixtures, jigs, and mechanical assemblies with 1/2-13 tapped holes in steel or aluminum bodies.

Installation Notes

Install using standard hex or spanner tooling appropriate for the plunger body. Ensure the tapped hole is clean and free of debris before threading in the plunger. Apply thread-locking compound only if the integrated locking element alone is insufficient for the application vibration level. Do not overtighten, as this can compress the spring beyond its rated travel and reduce end force accuracy.
