Hex nuts are six sided general purpose fasteners with internal screw threads.
The most common hexagonal fastener with internal threads that screws on to the shank of a bolt or a hex cap screw.
A nut designed specifically to thread on to small diameter machine screws. They are typically thinner than regular nuts with a finished side for butting up against the surface that does not need a washer.Thinner than a jam nut, this thin hex nut is used on panels or when a low profile is needed.
Flange nuts have a washer-like base to distribute pressure over a greater surface area and ensure the fastener stay tight. They are commonly used in manufacturing assembly lines where operations are speeded by using a single fastener instead of a nut and washer.
A flange nut is a nut that has a wide flange at one end that acts as an integrated, non-spinning washer. 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. These nuts are mostly hexagonal in shape and are made up of hardened steel and often coated with zinc.
The flange may be serrated to provide 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 must not be scratched. The serrations help in preventing the vibration of the nut from moving the fastener, thus maintaining the holding power of nut.
The flange nuts are sometimes provided with a swivel flange which helps in creating a more stable structure without affecting finished product like a serrated flange nut. Swivel flange nuts are mostly used in joining wood and plastic.  Sometimes both faces of the nut are serrated, permitting either side to lock.
