Gibraltar BBK-038-G Ball Knob 1 Inch Brass Threaded

Product Description

The GIBRALTAR BBK-038-G is a smooth-grip ball knob with a threaded hole mount, machined from solid brass in a natural finish. Measuring 1.0 inch in diameter, this knob accepts a 5/16-24 threaded fastener and provides a half-inch hole depth for secure engagement. It is designed for use in applications requiring a positive manual grip on a threaded shaft, stud, or machine screw. The natural brass construction resists corrosion and provides dependable durability in both light industrial and mechanical service environments. Technicians and maintenance professionals select this style of knob for control panels, fixtures, jigs, and equipment assemblies where hand-tightening is required.

The BBK-038-G suits residential and commercial mechanical, electrical, and HVAC applications where hand-adjustable hardware is needed. Typical installations include control panel adjustments, equipment access covers, fixture mounting points, and tool-room or maintenance shop assemblies. The smooth exterior grip surface allows consistent torque application by hand without the need for tools in routine adjustment scenarios. This knob is sold individually and is appropriate wherever a 5/16-24 threaded interface is present.

Installation Notes

Installation requires no special tools beyond hand tightening onto a compatible 5/16-24 threaded stud or machine screw. Confirm that the mating thread is clean and undamaged before installation to ensure full engagement across the half-inch hole depth. Do not exceed hand-tight torque, as over-tightening can strip the threaded insert or damage the knob body. Always de-energize or lock out any equipment before servicing panels or assemblies where this knob is being replaced or installed.
