Gibraltar G10-3081-B Wing Knob Female Insert 3/8-16

Product Description

The GIBRALTAR G10-3081-B is a female insert bar and wing knob designed for hand-tightening applications in jigs, fixtures, workholding setups, and industrial equipment. It features a 3/8-16 threaded insert, a head length of 2.25 inches, and a hub diameter of 0.75 inches. The knob body is molded from thermoplastic in black, providing a firm grip surface and corrosion resistance without metal-on-metal contact. The female insert accepts a 3/8-16 bolt or threaded stud to a depth of 0.5 inches. This type of hardware is commonly installed by machine technicians, fabricators, and maintenance trades on adjustable assemblies that require frequent manual repositioning.

This wing knob is suited for use on light to medium-duty adjustable equipment including drill press tables, band saw fences, woodworking jigs, and industrial machine guards. The thermoplastic construction keeps weight low and eliminates rust concerns in damp or washdown environments. The female insert style allows the knob to thread directly onto a fixed or protruding stud rather than accepting a separate bolt through a through-hole, making it the correct choice when the mating component is a stationary threaded post.

Key Features

• 3/8-16 female threaded insert for direct mounting onto threaded studs
• 0.5 inch thread engagement depth for secure hand-tight clamping
• 2.25 inch head length provides adequate leverage for tool-free tightening
• 0.75 inch hub diameter at the base for stable seating against mating surfaces
• Thermoplastic construction resists corrosion and reduces overall assembly weight
• Black finish blends with standard machine and fixture hardware

Compatibility

Designed as an OEM-style replacement or direct-fit component for fixtures, jigs, and adjustable industrial equipment using standard 3/8-16 threaded studs.

Installation Notes

Installation requires no tools under normal hand-tightening use. Ensure the mating threaded stud is clean and free of debris before threading on the knob. Do not use power tools to drive this knob onto the stud, as thermoplastic inserts can strip or crack under excessive torque. Follow applicable machinery safety standards when servicing adjustable equipment, and power down or de-energize any related machine before adjusting clamping hardware.
