Gibraltar G10-0030AT Ball Knob Female Insert 1 Inch

Product Description

The GIBRALTAR G10-0030AT is a female insert ball knob designed for use as a manual control handle on machinery, jigs, fixtures, and industrial equipment. Made from phenolic material, this knob offers solid grip performance and chemical resistance in light industrial and manufacturing environments. It features a smooth grip surface and a 5/16-18 female threaded insert, accepting standard fasteners for secure mounting. At 1 inch in diameter and 15/16 inch in height, it is a compact, low-profile knob suited for applications where space is limited but reliable hand actuation is required. Licensed trades, machine builders, and maintenance technicians install this type of hardware during equipment assembly or repair.

This ball knob is appropriate for use on control panels, machine tool handles, clamps, jigs, and general industrial fixtures requiring a threaded female insert mount. The red phenolic construction makes it easy to identify on busy shop floors or control assemblies. With a 1/2 inch hub diameter and 1/2 inch hole depth, it accommodates standard 5/16-18 threaded rods and bolts commonly found in light and medium-duty mechanical assemblies across industrial, HVAC, and facility maintenance applications.

Installation Notes

Installation is performed by machine builders, maintenance technicians, or qualified tradespeople during equipment assembly or repair. De-energize and lock out the equipment before replacing any control hardware. Thread the knob onto a compatible 5/16-18 stud or bolt, ensuring the insert is fully engaged and the knob seats flush against the mounting surface. Do not over-torque, as phenolic material can crack under excessive force.
