A flange nut is a nut that has a wide flange at one end that acts as an integrated, non-spinning washer. These nuts have serrations on the integrated washer giving it a "locking" characteristic. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface.
