Gibraltar G10-3089AE Wing Knob Thru Female Insert Locknut

Product Description

The GIBRALTAR G10-3089AE is a thermoplastic wing knob featuring a thru female insert locknut design, intended for hand-tightened fastening applications across a range of industrial, HVAC, and mechanical assembly tasks. The knob accepts a 3/8-16 thread with a hole size of 3/8-16x2x.47 and provides a 2-inch head length for a secure, ergonomic grip. Constructed from thermoplastic, this knob offers corrosion resistance and lightweight performance. The 0.75-inch hub diameter and black finish make it a clean, functional choice for panel mounting, enclosures, equipment guards, and adjustable component assemblies. Licensed trades and mechanical technicians typically specify this type of hardware for tool-free adjustment points in equipment that requires frequent repositioning or field servicing.

This wing knob is suited for residential and commercial mechanical assemblies where tool-free hand adjustment is required. Common applications include HVAC equipment panels, access door fasteners, filter frame assemblies, ductwork components, and general industrial enclosures. The thru female insert with locknut configuration allows the knob to thread onto a stud or bolt and lock in place, preventing loosening from vibration. The thermoplastic body is appropriate for indoor and light-duty protected outdoor environments where metal hardware would add unnecessary weight or create corrosion concerns.

Compatibility

Designed as an OEM-style replacement or direct-fit hardware component for assemblies requiring a 3/8-16 thru female insert locknut wing knob with a 2-inch head length.

Installation Notes

Installation is performed by hand without specialized tools. Ensure the mating stud or bolt is clean and free of burrs before threading the knob into place. Verify the locknut engagement is sufficient to prevent back-off under vibration prior to returning equipment to service. Thermoplastic knobs should not be over-torqued, as excessive force may crack the body.
