Gibraltar G10-3090-K Wing Knob Female Insert 3/8-16

Product Description

The GIBRALTAR G10-3090-K is a female insert bar and wing knob designed for tool-free or hand-tightened fastening applications. Molded from black thermoplastic, it provides a lightweight, corrosion-resistant grip point where a 3/8-16 threaded stud or bolt passes through a panel, bracket, or fixture. The knob features a 2-inch head length for adequate hand leverage, a 1/2-inch hole depth, and a 3/4-inch hub diameter. It is installed by licensed technicians, maintenance professionals, and fabricators who need a reliable, repeatable hand-knob fastener in light-duty assemblies, jigs, or equipment enclosures.

This wing knob suits a range of light industrial, HVAC panel, electrical enclosure, and equipment access door applications where frequent removal and reinstallation is required without tools. The female insert design accepts a 3/8-16 male threaded fastener, making it compatible with standard hardware used across HVAC, electrical, and general mechanical assemblies. It is well suited for residential and light commercial installations where hand-adjustable clamping or securing is needed on removable covers, guards, or access panels.

Installation Notes

This knob is installed by hand onto an existing 3/8-16 threaded stud or bolt. Ensure the mating stud is clean and free of debris before threading on the knob. Do not use power tools to drive or remove thermoplastic knobs, as overtightening can crack the hub or strip the insert. Follow equipment manufacturer guidelines for panel and access cover fastener torque requirements.
