Gibraltar 10018-G Threaded Ball Plunger 1/2-13 Steel

Product Description

The GIBRALTAR 10018-G is a threaded ball plunger designed for positioning, indexing, and light-duty locking applications in mechanical assemblies. The plunger features a 0.281-inch steel ball with a maximum reach of 0.072 inches, a 3/4-inch steel body with a 1/2-13 thread, and a black finish. Initial end force is 6 pounds and final end force is 12 pounds, providing consistent spring-loaded detent action. A built-in locking element secures the plunger in position after installation, preventing loosening due to vibration or movement. This part is installed by machinists, millwrights, maintenance technicians, and mechanical assemblers working on jigs, fixtures, tooling, and production machinery.

The 10018-G suits applications where a spring-loaded ball detent is needed to hold a sliding or rotating component in a repeatable position. Common install scenarios include tooling fixtures, machine slides, and assembly jigs in industrial and manufacturing environments. The locking element makes this plunger well suited for installations subject to vibration or frequent cycling. The black finish provides a basic level of surface protection for general shop and production environments.

Key Features

• 1/2-13 threaded body for standard tapped-hole installation
• 0.281-inch diameter steel ball with 0.072-inch maximum reach

Compatibility

Designed as a direct-fit threaded ball plunger for any 1/2-13 tapped hole application requiring a spring-loaded detent with a locking element.

Installation Notes

Installation requires a properly tapped 1/2-13 hole in the mating component. Thread the plunger in by hand first, then tighten with an appropriate wrench or hex key to engage the locking element. Ensure the mating surface or detent groove is aligned with the ball path before final tightening. De-energize or lock out any powered equipment before servicing assemblies that contain this plunger.
