Gibraltar 57093G Threaded Spring Plunger 5/8-11 Steel

Product Description

The GIBRALTAR 57093G is a standard threaded spring plunger designed to provide controlled, spring-loaded positioning and indexing in mechanical assemblies. Featuring a 5/8-11 thread size with a 1-1/2 inch thread length, this plunger delivers an initial end force of 10.5 pounds and a final end force of 25.5 pounds, making it suitable for moderate-load detent and positioning applications. The steel body is finished in black and incorporates a locking element to secure the plunger at the desired setting once installed. A Delrin nose reduces wear on mating surfaces. Machinists, toolmakers, and mechanical assembly technicians are the primary installers of this component.

The 57093G is used in jigs, fixtures, machine tools, and industrial equipment where repeatable spring-loaded positioning is required. Its 5/16 inch projection and 0.31 inch maximum plunger diameter make it appropriate for standard-clearance bores in tool steel or aluminum fixtures. The locking element is particularly valuable in high-vibration environments where plunger position must remain fixed between adjustments. Typical installations are found in manufacturing and fabrication settings requiring consistent part location.

Key Features

• 5/8-11 thread size with 1-1/2 inch thread and body length for deep engagement
• 10.5 lb initial end force and 25.5 lb final end force for moderate-load positioning
• Steel body with black finish for corrosion resistance in shop environments
• Delrin nose material minimizes wear on contact surfaces
• Integrated locking element holds plunger position under vibration
• 5/16 inch hex size allows installation and adjustment with standard hex tooling

Compatibility

Designed as a standard OEM-style threaded spring plunger for use in jigs, fixtures, and mechanical assemblies requiring 5/8-11 threaded bores with spring-loaded detent or indexing functionality.

Installation Notes

Install using a 5/16 inch hex key into a properly tapped 5/8-11 threaded bore. Ensure the bore is clean and free of debris before threading in the plunger to avoid cross-threading the steel body. Engage the locking element only after the plunger has been set to the correct projection depth. Do not over-torque the body, as this can damage the internal spring mechanism or deform the Delrin nose.
