This serves to distribute the pressure of the nut over the part being secured reducing the of damage to the part and making it less likely to loosen as a of an uneven fastening surface. The flange may be serrated to a locking action. The serrations are angled such that they keep the nut from rotating in the direction that would loosen the nut. Because of the serrations they cannot be used with a washer or on surfaces that cannot be scratched. The serrations help in avoiding vibration of nut and increase the holding power of nut.
