Gibraltar G10-0145-F Ball Knob Female Insert Phenolic

Product Description

The GIBRALTAR G10-0145-F is a phenolic ball knob with a female insert mount designed for use on machinery, equipment panels, and adjustable assemblies. The knob measures 1-3/8 inches in diameter and 1-3/8 inches in height, with a smooth grip surface and a black finish. It accepts a 1/2-20 threaded stem and provides a hole depth of 5/8 inches, allowing secure engagement with standard fasteners. The phenolic construction offers good resistance to heat and wear in light industrial and mechanical service applications. Machinists, equipment technicians, and maintenance professionals typically install this type of knob during assembly or adjustment hardware replacement.

This knob is suited for use on machine tool handles, jigs, fixtures, panel controls, and general industrial equipment where a hand-tightened control point is needed. The female insert style accepts a threaded stud or bolt already fixed in the equipment, making it a common choice for retrofit and replacement on existing assemblies. The smooth grip profile and compact hub diameter of 5/8 inches keep the form factor tight in confined panel layouts. Applications span light manufacturing, maintenance repair operations, and workshop equipment.

Installation Notes

Installation is typically performed by equipment technicians or maintenance personnel. Power down and de-energize any equipment before replacing knobs on live control panels or motorized assemblies. Thread the knob onto the existing stud by hand until firmly seated; do not use power tools, as overtightening can crack the phenolic body. Verify thread engagement depth does not exceed the 5/8 inch hole depth of the knob.
