Flange nuts, also known as pad nuts, tooth nuts, hexagonal flange nuts, flange nuts, etc. Most of them are used in pipe connections or workpieces that need to increase the nut contact surface. Flange nut (English: Flange nut) is a nut with a wide flange at one end, which can be used as an integral washer. 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. These nuts are mostly hexagonal in shape, made of hardened steel, and usually zinc-plated on the surface. 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.
