A flange nut is a nut that has a wide flange at one end that acts as an integrated, non-spinning washing machine. This is to distribute the pressure of the nut on the part to be attached, reduce the likelihood of damage to the component and to loosen less by an uneven mounting surface.
The flange can be serrated to allow a locking action. The serrations are angled so that they do not turn the nut in the direction that the nut would loosen Due to the serrations they cannot be used with a disc or on non-scratched surfaces. The serrations help to avoid vibrations of nuts and increase the holding force of the nut.
