Gibraltar 10003P-G Threaded Ball Plunger 6-40 Stainless Steel

Product Description

The GIBRALTAR 10003P-G is a threaded ball plunger designed for positioning, indexing, and light detent applications in mechanical assemblies. It features a 6-40 thread size, a stainless steel body, and a stainless steel ball measuring 0.078 inches in diameter. The plunger delivers 0.5 pounds of initial end force and 1 pound of final end force, making it well suited for low-force retention tasks. With a body length of 0.3125 inches and a maximum ball reach of 0.023 inches, this compact component fits tight-clearance installations. Machinists, tool and die makers, and mechanical assembly technicians are the primary installers.

This ball plunger is used in industrial and light mechanical applications where a spring-loaded ball is needed to locate, retain, or provide tactile feedback between moving parts. Typical installation scenarios include jigs, fixtures, tooling plates, and precision mechanical assemblies where repeatable positioning is required. The stainless steel construction makes it appropriate for environments where corrosion resistance or cleanliness standards must be maintained.

Key Features

• 6-40 thread size for installation into standard tapped holes
• Stainless steel body and ball for corrosion resistance
• 0.078 inch ball diameter with 0.023 inch maximum ball reach
• 0.5 pound initial end force and 1 pound final end force for light detent applications
• Compact 0.3125 inch body length suits tight-clearance assemblies
• No locking element, allowing straightforward threaded installation and removal

Compatibility

Designed as a standard threaded ball plunger for use in any mechanical assembly, jig, fixture, or tooling application requiring a 6-40 tapped hole and light spring-loaded ball retention.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a standard hex key or screwdriver appropriate for the plunger head style. Ensure the mating tapped hole is clean and correctly sized for 6-40 threads before installation. Do not overtighten, as this can restrict ball travel or damage the thread. No power source needs to be isolated for this purely mechanical component.
