Gibraltar ABK-049-G Ball Knob Threaded Hole Aluminum

Product Description

The GIBRALTAR ABK-049-G is a smooth-grip aluminum ball knob designed for use with threaded-hole mounting applications. It measures 1.88 inches in diameter and accepts a 3/8-16 threaded fastener with a hole depth of 0.75 inches. The knob is machined from aluminum with a natural finish, making it lightweight and corrosion-resistant for general industrial and mechanical service. It is commonly installed by maintenance technicians, machine builders, and equipment assemblers who need a reliable manual-adjustment or control knob on panels, fixtures, jigs, and machinery.

This ball knob suits a wide range of light industrial, manufacturing, and facilities-maintenance applications where hand-tightening or manual positioning is required. The threaded-hole configuration allows it to thread directly onto a machine screw or stud. Its smooth surface provides consistent hand grip without sharp edges, making it appropriate for frequent operator adjustment on equipment panels, clamping fixtures, and adjustment mechanisms found in production and maintenance environments.

Compatibility

Designed as a standard threaded-hole ball knob for use with 3/8-16 threaded studs or screws in general industrial, mechanical, and equipment-assembly applications.

Installation Notes

Installation is performed by maintenance technicians or equipment assemblers using standard hand tools. Before installing, confirm the mating stud or screw thread is clean and free of debris to prevent cross-threading. Thread the knob onto the fastener by hand to the required depth, ensuring full engagement within the 0.75-inch hole depth. Do not exceed the designed thread engagement depth, as over-driving can damage the internal threads.
