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

Product Description

The GIBRALTAR SW10-8-G is a standard threaded spring plunger designed for positioning, indexing, and light holding applications in mechanical assemblies. The steel body accepts a 1/2-13 thread with a 1-1/4 inch thread length. The plunger nose measures 0.248 inches in diameter with a 1/4 inch projection. Initial end force is 6.6 pounds and final end force is 17.4 pounds, making it suitable for moderate-load detent and locating tasks. No locking element is incorporated. Machinists, tool and die makers, and mechanical assembly technicians are the primary installers of this type of component.

This spring plunger is used in jigs, fixtures, machine tool assemblies, and industrial equipment where repeatable positioning or light retention is required. The 1/2-13 thread size fits tapped holes in standard steel, aluminum, and cast iron housings. Both the body and nose are steel construction, suited for general-purpose shop and production environments where the plunger is exposed to moderate loads and repeated cycling.

Key Features

• 1/2-13 thread size with 1-1/4 inch thread length for secure engagement in tapped holes
• Steel body and steel nose for durability in production and fixture applications
• 6.6 pound initial end force and 17.4 pound final end force for consistent detent performance
• 0.248 inch maximum plunger diameter with 1/4 inch projection
• No locking element — threads freely into tapped locations for easy positioning or removal
• Standard plunger length type for broad compatibility with common fixture designs

Compatibility

Designed as a standard OEM-style threaded spring plunger for use in tapped 1/2-13 holes in jigs, fixtures, and mechanical assemblies where a steel body and nose are appropriate.

Installation Notes

Installation is performed by threading the plunger into a properly tapped 1/2-13 hole using a hex key or spanner appropriate for the body style. Ensure the mating hole is clean and free of debris before installation. Do not overtighten, as excess torque can distort the body or restrict plunger travel. Verify plunger projection and force requirements are met before final assembly.
