Gibraltar BBK-043-G Ball Knob Threaded Hole Brass

Product Description

The GIBRALTAR BBK-043-G is a brass ball knob with a threaded hole mount, designed for use in mechanical, industrial, and trade applications where a secure, hand-operated grip is needed. Measuring 1.38 inches in diameter, this knob features a smooth grip surface and a 5/16-24 threaded hole with a 0.625-inch hole depth. The natural brass finish provides corrosion resistance and durability in demanding environments. It is commonly installed by mechanical technicians, equipment maintenance professionals, and trade contractors requiring reliable manual control components.

This ball knob is suited for use on machine tools, control panels, jigs, fixtures, and other equipment requiring hand-tightened adjustments. The 5/16-24 thread size is a standard fine-thread specification, making it compatible with a wide range of threaded studs and shafts in light industrial and trade settings. The compact 1.38-inch diameter is appropriate for equipment where space is limited but a positive grip is still required.

Installation Notes

Installation is performed by hand-threading the knob onto a compatible 5/16-24 stud or shaft. Ensure the mating stud is clean and free of debris before installation. Do not over-torque — brass threads can be damaged by excessive force. Power down or de-energize any associated equipment before servicing components in the control assembly.
