Gibraltar SW10-5-G Threaded Spring Plunger 5/16-18

Product Description

The GIBRALTAR SW10-5-G is a threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. It features a 5/16-18 thread size with a 1-inch thread length and a steel body and nose for durability in industrial and manufacturing environments. The plunger delivers 3 pounds of initial end force and 15 pounds of final end force, providing consistent spring tension across its 3/16-inch projection. This component is installed by machinists, maintenance technicians, and mechanical assemblers working on jigs, fixtures, tooling, and production equipment.

The SW10-5-G is suited for use in standard mechanical assemblies where a spring-loaded ball or nose plunger is needed to hold, locate, or index a moving part. The 5/16-18 thread allows installation into tapped holes in a wide range of materials including steel, aluminum, and plastic housings. With no locking element, the plunger threads directly into place and can be adjusted or removed without special tooling. Typical applications include fixture plates, machinery panels, drawer slides, and assembly jigs.

Key Features

• 5/16-18 thread size with 1-inch thread length for secure installation in standard tapped holes
• 3/16-inch plunger projection with 3-pound initial end force and 15-pound final end force
• Steel body and steel nose for wear resistance in production and industrial environments
• No locking element — threads directly into tapped hole without adhesive or retaining features
• Compact body length of 1 inch suits confined assembly spaces
• Maximum plunger diameter of 0.135 inches for precision fit in standard plunger bores

Compatibility

Designed as a direct-fit threaded spring plunger for tapped 5/16-18 holes in mechanical fixtures, jigs, tooling plates, and industrial equipment assemblies.

Installation Notes

Installation is performed by machinists or mechanical technicians using a standard hex wrench or spanner tool appropriate for the plunger body. Ensure the receiving tapped hole is clean and free of debris before threading in the plunger. De-energize or lock out any powered equipment before servicing assemblies that incorporate this plunger. Do not exceed the rated final end force when selecting this component for a given application.
