Gibraltar SSBK-048-G Ball Knob Threaded Hole Stainless

Product Description

The GIBRALTAR SSBK-048-G is a stainless steel ball knob with a threaded hole mount, designed for use as a manual control handle on industrial machinery, equipment panels, jigs, fixtures, and similar trade applications. The knob measures 1.38 inches in diameter and features a 1/2-20 threaded hole with a hole depth of 0.625 inches. The smooth grip surface and natural stainless steel finish make it suitable for environments where corrosion resistance and durability are priorities. It is installed by maintenance technicians, machine builders, and equipment service professionals who need a reliable hand-tightened knob for adjustment or locking mechanisms.

This ball knob is appropriate for use on industrial equipment, control assemblies, workholding fixtures, and mechanical adjustment points requiring a 1/2-20 threaded fastener interface. The compact 1.38-inch diameter suits panel-mounted applications where space is limited. The stainless steel construction makes it a practical choice for wash-down, outdoor, or corrosion-prone environments common in industrial maintenance and trade settings.

Installation Notes

Installation is performed by threading the knob directly onto a 1/2-20 threaded stud, shaft, or bolt by hand or with light tool assistance. Confirm the mating thread specification before installation to avoid cross-threading. No special tools or trade licenses are required, but the installer should ensure the knob seats fully to the required hole depth for reliable engagement. Degrease mating threads if a locking compound is to be applied per the equipment manufacturer's guidance.
