Gibraltar 10021P Threaded Ball Plunger 5/8-11 Steel

Product Description

The GIBRALTAR 10021P is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 5/8-11 threaded body measuring 0.984 inches in body length with a 0.375 inch steel ball and a maximum ball reach of 0.096 inches. The steel body carries a black finish and is color-coded purple for easy identification. Initial end force is 9 pounds and final end force is 18 pounds, making it suitable for moderate-load positioning tasks. This type of component is typically installed by millwrights, machine technicians, and maintenance professionals working on fixtures, jigs, tooling, and mechanical assemblies.

The 10021P is used in industrial and commercial applications where a spring-loaded ball detent is needed to hold or index a moving component in position. Common install scenarios include tool fixtures, sliding mechanisms, door hardware, and light industrial equipment. The plunger threads directly into a tapped hole, allowing straightforward integration into existing assemblies without secondary fasteners or special mounting hardware.

Key Features

• 5/8-11 threaded body for direct installation into standard tapped holes
• 0.375 inch diameter steel ball provides consistent detent engagement
• 9 pound initial end force and 18 pound final end force for moderate-load positioning
• Maximum ball reach of 0.096 inches limits over-travel during engagement
• Steel body with black finish for durability in light industrial environments
• No locking element — allows removal and repositioning without thread adhesive

Compatibility

Designed as a standard threaded ball plunger for use in any assembly accepting a 5/8-11 tapped hole. Consult fixture or equipment specifications to confirm thread engagement depth and required end force before installation.

Installation Notes

Installation requires a properly tapped 5/8-11 hole in the receiving material. Thread the plunger in by hand first to confirm alignment, then tighten with an appropriate wrench — do not overtighten, as excess torque can damage the spring mechanism or thread engagement. Verify that ball reach and end force ratings match the load and travel requirements of the application before finalizing installation.
