Wing Nut

The key features shown in the image are:

• m: The overall width or diameter of the wing nut

• h: The height or thickness of the wing nut

• d: The diameter of the central threaded hole

The most distinctive characteristic of a wing nut is the pair of projecting "wings" or flanges on either side of the hexagonal nut head. These wing-like flanges allow the nut to be easily tightened or loosened by hand, without the need for tools.

Wing nuts are designed for applications where frequent adjustment or removal of the nut is required, such as on clamping mechanisms, knobs, and other easy-access fasteners. The large wing-like projections provide enhanced grip and leverage compared to a standard hex nut.

Wing nuts are commonly found in woodworking, machinery, and consumer products where tool-free tightening and loosening is advantageous. They are often made of softer materials like plastic or aluminum to facilitate easy hand operation.

The specific dimensions provided in the drawing, such as the overall diameter (m), height (h), and hole size (d), would allow this particular wing nut to be properly specified and manufactured.
