Gibraltar 57001G Threaded Spring Plunger 6-32 Steel

Product Description

The GIBRALTAR 57001G is a threaded spring plunger designed for precise indexing, positioning, and locking applications in mechanical assemblies. It features a 6-32 thread size with a 17/32-inch thread length and a standard plunger projection of 1/16 inch. The plunger diameter measures 0.045 inches. Built with a steel nose and steel body finished in black, this unit includes a locking element to hold the plunger in the retracted position when needed. Initial end force is 1.5 pounds and final end force is 4.5 pounds. Installed by machinists, maintenance technicians, and mechanical assemblers, it is suited for light-duty spring-loaded positioning tasks.

This spring plunger is used in precision machining fixtures, jigs, automation equipment, and general mechanical assemblies where repeatable part positioning or detent action is required. The locking element makes it well suited for applications where the plunger must be held flush during part loading before release. Typical installations are found in manufacturing environments, tooling setups, and equipment panels requiring controlled spring-loaded engagement.

Key Features

• 6-32 thread size with 17/32-inch thread length for standard threaded installation
• Locking element holds plunger in retracted position during assembly or part loading
• Steel body and steel nose for durability in mechanical applications
• 1.5-pound initial end force and 4.5-pound final end force for light-duty spring engagement
• Maximum plunger diameter of 0.045 inches with standard projection of 1/16 inch
• Black finish for corrosion resistance and clean appearance

Compatibility

Designed as an OEM-style replacement or new-installation spring plunger for mechanical assemblies requiring a 6-32 threaded spring plunger with a locking element and standard projection.

Installation Notes

Installation is performed by machinists or mechanical technicians using standard threading tools appropriate for a 6-32 tap. Ensure the receiving threaded bore is clean and properly tapped to depth before installation. Do not overtighten, as this can damage the locking element or restrict plunger travel. De-energize or lock out any equipment before servicing assemblies that contain spring plungers.
