Gibraltar G10-3093 Wing Knob 1/4-20 Female Insert

Product Description

The GIBRALTAR G10-3093 is a female insert bar and wing knob made from thermoplastic, designed for hand-tightening applications where a threaded insert accepts a bolt or stud. The knob features a 1/4-20 thread hole, a 3-inch head length, and a 0.5-inch hole depth, making it suitable for quick-release fastening setups on machinery, fixtures, jigs, and enclosures. The hub diameter measures 25/32 inches. Its black thermoplastic construction provides corrosion resistance and a firm grip surface without requiring tools for installation or adjustment. Maintenance technicians, fabricators, and machine builders typically install this type of hardware during assembly or field adjustment work.

This wing knob is used in industrial, commercial, and light manufacturing environments where frequent access panels, guards, or adjustable components need to be secured and released by hand. Common applications include equipment enclosures, positioning fixtures, conveyor guards, and control panel covers. The female insert design threads directly onto a male stud or bolt, locking the component in place without additional hardware.

Installation Notes

Installation requires no tools — thread the knob onto an existing 1/4-20 male stud or bolt by hand. Verify stud engagement depth does not exceed the 0.5-inch hole depth before final assembly. Avoid over-torquing, as thermoplastic inserts can crack under excessive force. Follow applicable machinery safety standards when used on equipment panels or guards that require secure retention.
