Gibraltar 10010-G Threaded Ball Plunger 1/4-20 Steel

Product Description

The GIBRALTAR 10010-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 1/4-20 thread size, a steel body, and a steel ball measuring 0.125 inches in diameter. The ball extends a maximum of 0.035 inches and delivers 4 pounds of initial end force, increasing to 12 pounds of final end force. A built-in locking element secures the plunger in place after installation, preventing loosening under vibration or repeated cycling. Machinists, toolmakers, and maintenance technicians install this type of component in fixtures, jigs, slides, and automated equipment where repeatable part location is required.

This ball plunger is suited for use in manufacturing fixtures, machine tool components, and industrial positioning assemblies. The 1/4-20 thread allows installation into standard tapped holes without special tooling. The steel construction handles moderate load cycles in dry or lightly lubricated environments. At 0.5313 inches body length, it fits into shallow panel or fixture boss configurations. The locking element eliminates the need for thread-locking compound in most standard applications.

Key Features

• 1/4-20 thread size for installation in standard tapped holes
• 0.125 inch steel ball diameter with 0.035 inch maximum ball reach
• 4 pound initial end force and 12 pound final end force for controlled detent action
• Integrated locking element prevents back-out under vibration
• Steel body and steel ball for durability in industrial service
• Compact 0.5313 inch body length fits shallow boss or panel installations

Compatibility

Designed as a standard 1/4-20 threaded ball plunger for use in industrial fixtures, jigs, tooling plates, and positioning assemblies that require a tapped hole of 1/4-20 thread form.

Installation Notes

Installation requires a properly tapped 1/4-20 hole in the mating component. Use an appropriate hex key or drive tool to thread the plunger to full engagement before the locking element seats. Ensure the bore is clean and free of chips or debris before installation. The locking element is a one-time or limited-use feature on many designs, so plan the final installed position before fully driving the plunger home.
