Flange Nut Inch Series

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. The nuts are mostly hexagonal in shape and often coated with zinc. They help in preventing the vibration of the nut from moving the fastener, thus maintaining the holding power of nut.
