Wing knobs are designed to give good leverage with minimal grip strength, making them ideal for applications that require frequent tightening and loosening, or in more precision applications. These knobs do not require tools and can be easily adjusted using only a thumb and forefinger, similar to thumb screw knobs, but with an added arm.

Black Polypropylene Female Wing Knob has a Threaded Insert for mounting onto 1/4-20 threads. The Wedge wing design is easily gripped for frequent tightening.
