Gibraltar G10-3009-U Fluted Knob 1.5 in Phenolic Threaded Stem

Product Description

The GIBRALTAR G10-3009-U is a fluted knob with a 1.5-inch head diameter, designed for use with threaded stem applications. Constructed from phenolic material with a glossy finish, this knob provides a firm grip and durable surface for hand-operated adjustments on machinery, fixtures, and industrial equipment. The 1/4-20 threaded stem is the industry-standard fastener thread for light-duty knob applications. Technicians and assemblers in mechanical, electrical, and industrial maintenance environments regularly install this type of hardware when building or servicing control panels, enclosures, and equipment housings.

This fluted knob is suited for use in panel assembly, machine adjustment, and equipment maintenance scenarios where a hand-tightened, tool-free fastener is required. The phenolic body withstands moderate heat and resists oils and common solvents, making it appropriate for light industrial and commercial service environments. The glossy finish provides a clean appearance for visible installations on control equipment and cabinets.

Key Features

Compatibility

Designed as a standard 1/4-20 threaded stem fluted knob for use in panel assembly, equipment housing, and light industrial applications requiring hand-operated fastening.

Installation Notes

Installation requires no special tools — thread the stem into the mating nut or tapped hole and tighten by hand. Ensure the receiving thread is clean and free of debris before installation. Do not use a wrench or power driver on the knob body, as overtightening may crack the phenolic material. Follow equipment manufacturer guidelines for torque and engagement depth on the mating component.
