Gibraltar G10-3088 Female Insert Wing Knob 1/4-20

Product Description

The GIBRALTAR G10-3088 is a female insert bar and wing knob designed for manual fastening applications where tool-free adjustment is required. Built from black thermoplastic, this knob accepts a 1/4-20 threaded insert and features a 2.5-inch head length for a wide grip surface. The 0.5-inch hole depth accommodates standard fastener engagement, while the 0.75-inch hub diameter provides a stable base. This style of knob is commonly installed by industrial technicians, machine builders, and equipment maintenance professionals who need a secure, repeatable hand-tightened connection.

The G10-3088 wing knob is suited for light-duty clamping, panel mounting, and equipment adjustment applications across industrial, commercial, and manufacturing environments. Its wing-style profile allows for quick loosening and tightening without tools, making it practical for frequently adjusted assemblies. The female insert design threads onto an exposed male stud or bolt, which is a common configuration in jig fixtures, enclosure panels, and machinery guards.

Key Features

• 1/4-20 female insert thread for standard fastener compatibility
• 2.5-inch head length for broad grip surface during hand tightening
• 0.5-inch hole depth for reliable thread engagement
• 0.75-inch hub diameter for stable seating at the mounting point

Compatibility

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

Installation Notes

Installation is performed by hand or with light assistance from standard hand tools. Ensure the mating male thread is clean and free of debris before threading the knob onto the stud. Do not over-torque, as thermoplastic inserts can crack under excessive force. Verify thread engagement depth does not exceed the 0.5-inch hole depth of the knob.
