Gibraltar 10004-G Threaded Ball Plunger 8-36 Ss

Product Description

The GIBRALTAR 10004-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features an 8-36 thread size, a stainless steel body, and a stainless steel ball measuring 0.093 inches in diameter. The body length is 0.3438 inches (11/32 inches), with a maximum ball reach of 0.025 inches. Initial end force is 0.5 pounds and final end force is 1.25 pounds. A built-in locking element secures the plunger in place once installed. This part is identified by a purple color code for quick field identification during assembly or maintenance work.

Threaded ball plungers like the 10004-G are used in jigs, fixtures, machine tool components, and precision mechanical assemblies where repeatable positioning or spring-loaded detent action is required. The 8-36 thread makes this plunger suited for compact, fine-thread applications typical in light manufacturing, instrumentation, and industrial equipment maintenance. Machinists, millwrights, and mechanical technicians are the primary installers in both production and repair settings.

Key Features

• 8-36 thread size for fine-thread, compact installation
• Stainless steel body and ball for corrosion resistance
• 0.093-inch ball diameter with 0.025-inch maximum ball reach
• 0.5 lb initial end force and 1.25 lb final end force for light-duty detent action
• Integrated locking element to prevent backing out after installation
• Purple color code for quick identification in multi-plunger assemblies

Compatibility

Designed as a standard threaded ball plunger for use in mechanical assemblies, jigs, and fixtures requiring an 8-36 thread and stainless steel construction.

Installation Notes

Installation requires threading the plunger into a pre-tapped 8-36 hole using an appropriate hex key or driver. Ensure the mating hole is clean and properly tapped to full thread depth before installation. The locking element is engaged during final torquing — avoid over-tightening, which can deform the locking feature or restrict ball movement. Always verify ball travel and detent force after installation before returning the assembly to service.
