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.

M8 - M12 Diameter JIS (Japanese Industrial Standard) Flange nuts have smaller hex sizes than ISO and ANSI type bolts and are commonly used for import cars, auto repair, truck, car, and motorcycle frames, vehicle engines, transmission and exhaust. They are also mostly used for automotive and fastening applications such as steering and suspension parts, cylinder, and flywheels, and also for high strength mechanical applications and forged parts.
