Gibraltar 10016-G Threaded Ball Plunger 3/8-16 Steel

Product Description

The GIBRALTAR 10016-G is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 3/8-16 thread, a 0.187-inch steel ball, and a body length of 0.625 inches. The integrated locking element secures the plunger in position after adjustment, preventing loosening under vibration or repeated cycling. Initial end force is 6 pounds and final end force is 21 pounds, providing a defined tactile detent feel. Both the body and ball are steel construction for durability in industrial and manufacturing environments. This plunger is installed by machinists, toolmakers, and maintenance technicians.

Ball plungers of this type are commonly used in jigs, fixtures, machine tool slides, and assembly tooling where a repeatable detent or indexing action is required. The 3/8-16 threaded body installs into a tapped hole in steel, aluminum, or plastic workpieces. The locking element allows the plunger force to be set and locked without additional locking hardware. Typical applications include drawer stops, positioning fixtures, and panel latching mechanisms in light industrial and precision manufacturing settings.

Compatibility

Designed as a standard threaded ball plunger for use in any application requiring a 3/8-16 tapped mounting hole and a steel-body detent or indexing element.

Installation Notes

Installation requires a properly tapped 3/8-16 hole in the mating workpiece. Thread the plunger in using a hex key or spanner appropriate for the head style, then engage the locking element to fix the desired ball protrusion. Power down or de-energize any associated equipment before servicing fixtures or assemblies containing this plunger. Avoid over-torquing, which can damage the locking element or distort the threaded bore.
