Gibraltar BBK-035-G Ball Knob 1 Inch Brass Threaded

Product Description

The GIBRALTAR BBK-035-G is a brass ball knob designed for threaded-hole mounting applications. It features a 1-inch diameter sphere with a smooth grip surface and accepts a 1/4-20 threaded fastener with a 0.5-inch hole depth. The knob is finished in a natural brass color, making it suitable for use in mechanical assemblies, equipment panels, and control installations where a hand-operable knob is required. Typical installers include HVAC technicians, electricians, and millwrights who need a reliable grip point on adjustable components or panel hardware.

This ball knob is commonly used in light industrial, commercial, and trade equipment applications where hand adjustment is needed without tools. It fits into control panels, enclosures, jigs, fixtures, and mechanical assemblies. The threaded-hole design allows direct installation onto a matching 1/4-20 threaded stud or shaft. Its compact 1-inch diameter is well suited for tight spaces where larger knobs would interfere with adjacent components.

Key Features

• 1-inch diameter brass ball knob with smooth grip surface
• Threaded-hole mount accepts 1/4-20 fasteners
• 0.5-inch hole depth for secure thread engagement

Compatibility

Designed as an OEM-style replacement or new-installation component for threaded-stud assemblies using 1/4-20 fastener threads in light industrial and trade equipment applications.

Installation Notes

Installation requires no special tools — thread the knob directly onto a 1/4-20 stud or bolt by hand. Ensure thread engagement reaches the full 0.5-inch hole depth before applying any load to the knob. Do not use power tools to drive the knob onto the stud, as this may damage the brass threads. Verify the mating stud thread class and condition before installation to ensure proper fit and retention.
