Gibraltar G10-0033-V Ball Knob Female Insert 1-3/8 in

Product Description

The GIBRALTAR G10-0033-V is a phenolic ball knob with a female insert mount, designed for use as a hand-tightened control or adjustment knob in light industrial, mechanical, and equipment assembly applications. The knob measures 1-3/8 inches in diameter and 1-9/32 inches in height, with a 3/8-16 threaded female insert and a hole depth of 0.5 inches. The smooth grip surface and compact hub diameter of 5/8 inches make it suited for applications where operators need quick, tool-free adjustments. Licensed tradespeople, equipment assemblers, and maintenance technicians are the typical installers.

This ball knob is commonly used in industrial equipment panels, machine tool setups, jigs, fixtures, and HVAC or electrical enclosure assemblies where a reliable hand-operated fastener is needed. The red phenolic construction provides durability in moderate-temperature environments and offers good chemical resistance for workshop and light-duty service conditions. The female insert style allows the knob to thread directly onto a male-threaded stud or bolt, making installation straightforward without additional hardware.

Installation Notes

Installation is performed by threading the knob onto an exposed 3/8-16 male stud or bolt by hand. Ensure the mating stud does not exceed the 0.5 inch hole depth to avoid bottoming out before the knob seats. De-energize or lock out any equipment before servicing panels or assemblies that incorporate this knob. Do not apply power tools to tighten, as over-torquing may crack the phenolic body.
