Gibraltar SSBK-043-G Ball Knob Threaded Hole 1.38 in

Product Description

The GIBRALTAR SSBK-043-G is a stainless steel ball knob designed for applications requiring a threaded hole mount. With a diameter of 1.38 inches and a 5/16-24 thread size, this knob fits securely into standard threaded assemblies. The smooth grip surface provides reliable hand control without the need for tools. At 0.36 pounds, it is a compact and solid hardware component suited for machine controls, jigs, fixtures, and equipment panels. It is typically installed by machinists, maintenance technicians, and equipment fabricators in industrial and light commercial settings.

This ball knob is well-suited for use on manual adjustment mechanisms, clamping fixtures, and control panels where a finger-tightened knob is needed. The natural stainless steel finish resists corrosion, making it appropriate for environments exposed to moisture or cleaning agents. The 5/8-inch hole depth provides sufficient thread engagement for secure fastening without bottoming out on standard threaded studs.

Key Features

• Stainless steel construction for corrosion resistance in wet or industrial environments
• Threaded hole mount with 5/16-24 thread size for secure attachment
• 1.38-inch diameter ball provides comfortable hand grip for manual adjustments
• Smooth grip surface for clean, tool-free operation

Compatibility

Designed as an OEM-style replacement or direct-fit component for equipment and fixtures using a 5/16-24 threaded stud mount requiring a standard ball knob.

Installation Notes

Installation requires threading the knob onto a 5/16-24 male stud by hand. Ensure the mating stud length does not exceed the 5/8-inch hole depth to avoid bottoming out and preventing full seating. De-energize or lock out any equipment before servicing control knobs on powered machinery. A thread-locking compound may be applied to the stud if vibration is a concern in the application.
