Gibraltar SW10-8A-PT-G Threaded Spring Plunger 1/2-13

Product Description

The GIBRALTAR SW10-8A-PT-G is a standard threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The plunger features a 1/2-13 thread with a 1-1/4 inch thread length and a maximum plunger diameter of 0.248 inches. Projection measures 0.250 inches. Initial end force is 2.70 pounds and final end force is 9.30 pounds. Both the nose and body are constructed from steel, and the unit includes a locking element to secure the plunger position under load. This part is installed by machinists, maintenance technicians, and mechanical assemblers working with fixtures, jigs, and production tooling.

This spring plunger is suited for use in precision fixturing, machine tooling, and general mechanical assembly where a repeatable detent or stop position is required. The locking element makes it appropriate for applications where the plunger must remain set during operation without drifting. Standard thread sizing allows straightforward installation into tapped holes in steel, aluminum, or similar substrates. Typical use cases include production jigs, assembly fixtures, and equipment panels requiring a controlled spring-loaded stop.

Key Features

• 1/2-13 thread size with 1-1/4 inch thread length for standard tapped-hole installation
• Steel nose and body construction for durability in industrial environments
• Locking element included to hold plunger position under load
• 2.70 pound initial end force and 9.30 pound final end force for controlled spring resistance
• Maximum plunger diameter of 0.248 inches with 0.250 inch projection

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard 1/2-13 tapped hole applications in mechanical fixturing and assembly tooling.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped 1/2-13 hole using an appropriate wrench or hex tool. Ensure the mating bore is clean and free of debris before installation. Disengage or de-energize any associated machinery before servicing or replacing spring plungers in active fixtures. Do not exceed the rated final end force when compressing the plunger, as overloading may damage the internal spring or locking element.
