The GIBRALTAR SBK-056-G is a steel ball knob with a threaded hole mount, designed for use as a hand-tightened control or adjustment knob on machinery, equipment panels, fixtures, and jigs. The knob measures 1 inch in diameter with a 3/8-16 threaded hole and a hole depth of 0.5 inches. The smooth grip surface and natural steel finish make it suitable for general industrial and mechanical applications. Installers in HVAC, electrical, and mechanical trades use ball knobs like this one for securing access panels, adjusting damper linkages, and fastening equipment covers where tool-free operation is preferred.
This ball knob is suited for light-duty to medium-duty industrial applications where a compact, hand-operated fastener is needed. It fits standard 3/8-16 threaded rod or stud configurations commonly found in equipment assemblies, control panels, and fabricated fixtures. The natural steel finish is appropriate for interior or protected environments. Typical installations include panel mounting, jig and fixture assembly, and equipment adjustment points in commercial and industrial settings.
Designed as an OEM-style replacement or direct-fit ball knob for equipment and assemblies using a 3/8-16 threaded stud or rod configuration.
Thread the knob onto a 3/8-16 stud or rod by hand until snug. Ensure the mating thread is clean and free of burrs before installation. No special tools are required for standard hand-tightening applications. Avoid over-torquing, as the knob is intended for tool-free hand operation.
