Gibraltar G10-3088-B Female Insert Wing Knob 3/8-16

Product Description

The GIBRALTAR G10-3088-B is a female insert bar and wing knob designed for hand-tightening applications where a threaded fastener point is needed without tools. The knob accepts a 3/8-16 thread with a 0.5 inch hole depth and features a 2.5 inch head length for a secure, comfortable grip. Constructed from black thermoplastic, it offers corrosion resistance and lightweight durability. The 0.75 inch hub diameter provides a stable interface between the knob body and the mating component. This type of hardware is commonly installed by machine builders, equipment technicians, and fabricators working on jigs, fixtures, enclosures, and industrial assemblies.

The G10-3088-B is suited for use in light to medium-duty clamping and adjustment applications. Its wing-style profile allows for fast hand operation without tools, making it well-suited for panels, guards, or adjustment points that require frequent loosening and tightening. The thermoplastic body holds up in general industrial and shop environments where metal knobs are unnecessary or where weight reduction is a priority.

Compatibility

Installation Notes

Installation is typically performed by hand or with light mechanical assistance. Ensure the mating stud or threaded post is clean and free of damage before threading the knob on. Do not use power tools or wrenches on the knob body, as thermoplastic can crack under excessive torque. Verify thread engagement depth does not exceed the 0.5 inch hole depth to avoid bottoming out on the insert.
