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

Product Description

The GIBRALTAR SW10-5AFS-G is a short-pattern threaded spring plunger designed for indexing, positioning, and light-duty holding applications in mechanical assemblies. It features a 5/16-18 threaded body with a 5/8 inch thread length and a steel nose and body construction. The plunger delivers 0.5 lb of initial end force and 4.5 lb of final end force, making it suitable for applications that require controlled, repeatable spring-loaded engagement. This component is installed by machinists, tool-and-die technicians, and mechanical assemblers working on fixtures, jigs, and production equipment.

This spring plunger is suited for use in industrial machinery, assembly fixtures, and precision positioning equipment where a threaded, spring-loaded detent is required. The short plunger length and 3/16 inch projection keep the installed profile compact, making it a practical choice in space-constrained housings and fixture plates. It is sold individually and is compatible with standard tapped holes machined to 5/16-18 specifications.

Key Features

• 5/16-18 thread size with 5/8 inch thread length for standard tapped hole installation
• Short plunger length designation keeps installed profile low-profile
• 3/16 inch plunger projection for controlled detent engagement
• 0.5 lb initial end force and 4.5 lb final end force for light-duty indexing
• Steel body and nose material for durability in industrial environments
• No locking element — installs and adjusts without thread-locking features

Compatibility

Designed as a direct-install spring plunger for any application with a standard 5/16-18 tapped hole requiring a short-projection, spring-loaded detent or positioning element.

Installation Notes

Installation requires a properly tapped 5/16-18 hole and a standard hex wrench or screwdriver suitable for the plunger drive style. Ensure the assembly is de-energized and at rest before installing or adjusting spring plungers in active machinery. Do not overtighten, as excessive torque can distort the plunger body or affect spring performance. Follow applicable machinery safety and maintenance standards for fixture and tooling work.
