Gibraltar G10-3086 Female Insert Wing Knob 1/4-20

Product Description

The GIBRALTAR G10-3086 is a female insert bar and wing knob designed for tool-free hand tightening in industrial, mechanical, and fixture assembly applications. The knob features a 1/4-20 threaded insert with a 3/8-inch hole depth, accepting standard 1/4-20 machine screws and bolts. The head measures 1-1/4 inches in length with a 5/8-inch hub diameter. Constructed from black thermoplastic, this knob provides a lightweight, corrosion-resistant grip point suitable for repeated adjustment cycles. The wing-style profile allows for solid finger torque without tools. Fabricators, machine builders, and assembly technicians use this type of fastener hardware in jigs, fixtures, and equipment panels.

This knob is suited for light to medium-duty clamping and adjustment applications where frequent repositioning is required. Typical installations include fixture plates, guards, enclosures, and mechanical assemblies that require hand-tightened fastening points. The 1/4-20 thread size is one of the most common unified coarse thread standards in North American industrial hardware, making this knob a straightforward drop-in component for existing threaded hardware setups. Its black thermoplastic construction resists oils and common shop chemicals.

Installation Notes

Installation is performed by hand threading the knob onto a 1/4-20 screw or stud. Ensure the mating thread is clean and free of debris before engagement to avoid cross-threading the thermoplastic insert. Do not use power tools or wrenches to drive this knob, as overtightening can crack the thermoplastic body or strip the insert. This part is typically installed by fabricators, assembly technicians, or maintenance personnel and requires no special tools or trade licensing.
