Gibraltar 1RM6A206A8Z002G Fluted Knob Female Insert

Product Description

The GIBRALTAR 1RM6A206A8Z002G is a fluted knob with a female insert designed for manual adjustment applications in industrial, mechanical, and equipment assembly settings. The knob body is molded from thermoplastic elastomer, which provides a firm yet comfortable grip surface for hand-tightening operations. The female insert accepts a 5/16-18 threaded fastener, making it straightforward to mount onto standard threaded studs, rods, or machine screws. With a head diameter of 1.68 inches, the knob offers adequate torque leverage for finger-tightening without tools. Machinists, equipment assemblers, and maintenance technicians are the typical installers.

This fluted knob is suited for use on machine tool fixtures, jigs, guards, control panels, and general-purpose industrial equipment where a hand-adjustable fastening point is needed. The thermoplastic elastomer construction makes it appropriate for both indoor and light-duty environments where chemical or UV exposure is limited. The 5/16-18 female thread matches one of the most common thread sizes found in North American industrial fastener applications, so fitment into existing hardware is generally straightforward.

Installation Notes

Installation requires no special tools — thread the female insert onto a 5/16-18 stud or fastener by hand. Ensure the mating thread is clean and free of debris before engagement. Power down or de-energize any equipment before accessing panels or guards where this knob is being installed or replaced. Do not apply wrench torque directly to the knob body, as the thermoplastic material is intended for hand operation only.
