Flange Nuts are fasteners that look like a standard hex nut but the bottom has a widened circular flange or skirt that acts as a built-in washer and distributes the holding power of the nut evenly across the surface for a more secure fastening solution. These types of nuts are designed to remove the deficiencies commonly associated with the use of washers.

The serrations on the nut are meant to dig into the surface of the work to create a more secure connection that resists loosening which also makes it a popular choice with electronics fasteners as they are less prone to damaging fragile, soft metal surfaces as compared to a traditional nut.
