Gibraltar G10-3085 Female Insert Wing Knob 1/4-20

Product Description

The GIBRALTAR G10-3085 is a female insert bar and wing knob designed for tool-free fastening and adjustment in light mechanical assemblies. Made from black thermoplastic, it accepts a 1/4-20 threaded fastener with a hole depth of 3/8 inches and features a hub diameter of 1/2 inch. The overall head length measures 1-1/8 inches, and the height is 3/4 inch. The wing-style grip allows hand-tightening without tools, making it well-suited for panel mounting, jigs, fixtures, and enclosure hardware. Electricians, panel builders, HVAC technicians, and mechanical assemblers commonly install this type of hardware in low-torque clamping and positioning applications.

This knob is used in residential and commercial equipment assemblies where frequent manual adjustment or removal is required. Typical applications include equipment panels, access covers, guide rails, and fixture frames. The female insert design threads directly onto a stud or bolt, providing a secure grip without permanent fastening. Its thermoplastic construction resists corrosion and is suitable for indoor mechanical environments.

Key Features

• 1/4-20 female thread insert for standard fastener compatibility
• 3/8 inch hole depth provides sufficient thread engagement for light-duty clamping
• 1/2 inch hub diameter for centered, stable seating on mounting surfaces
• Wing-style grip allows hand-tightening without tools
• Thermoplastic construction resists corrosion and chemical exposure
• Black finish for clean, finished appearance in panel and enclosure applications

Compatibility

Designed as an OEM-style replacement or standard hardware component for assemblies using 1/4-20 threaded studs or bolts requiring a hand-adjustable wing knob with a female insert.

Installation Notes

Installation requires no special tools — thread the knob onto a 1/4-20 stud or bolt by hand. Ensure the mating stud length does not exceed the 3/8 inch hole depth to avoid bottoming out before adequate clamping force is achieved. Power down or de-energize any equipment before servicing panels or enclosures where this knob is used. Do not exceed the hand-tightening torque appropriate for thermoplastic hardware.
