The flange nut has a wide flange at one end, which can be used as an integral gasket. This is used to distribute the pressure of the nut on the fixed part, thereby reducing the possibility of damage to the part and making it less likely to loosen due to the uneven fastening surface. It is mostly hexagonal, made of hardened steel, and usually coated with zinc. With rotating flange, it helps to form a more stable structure without affecting the finished product like the serrated flange nut.
In many cases, the flange is fixed and rotates with the nut. The flange can be serrated to provide a locking effect. The serrations are angled so that the nut does not rotate in the direction of loosening the nut. Because of the serrations, they cannot be used with washers or on scratched surfaces. The serration helps prevent the vibration of the nut from moving the fastener, thereby maintaining the retention force of the nut.
