Gibraltar SSBK-047-G Ball Knob Threaded Hole 1.38 in

Product Description

The GIBRALTAR SSBK-047-G is a stainless steel ball knob with a threaded hole mount, designed for use on machine handles, jigs, fixtures, and industrial equipment where a secure, hand-tightened grip is needed. The knob measures 1.38 inches in diameter and features a smooth grip surface with a natural stainless steel finish. The threaded hole accepts a 1/2-13 thread and provides a hole depth of 0.625 inches. Its stainless steel construction resists corrosion, making it suitable for wet, washdown, or outdoor service environments where hardware longevity matters.

This ball knob is commonly used in light industrial, mechanical, and trade applications including HVAC equipment panels, plumbing fixture assemblies, pump stations, and shop machinery. It is appropriate for any installation requiring a compact, hand-operated control knob where tool-free adjustment is preferred. The natural stainless finish blends with standard hardware in both shop and field environments.

Installation Notes

Installation is hand-tightened onto any compatible 1/2-13 threaded stud or bolt. Ensure the mating thread is clean and free of debris before installation. No special tools are required for standard hand-tightened applications; a wrench should only be used if torque specifications for the host equipment call for it. Thread engagement should fully utilize the available 0.625 inch hole depth to ensure a secure fit.
