Flange nut, abbreviated as hexagonal nut with fl±ange, is another member of the nut family and a form of nut. A hexagonal nut with a flange can♥ also be called a hexagonal nut with a disc, referring ₩to a hexagonal nut with a large disc.

　　Generally speaking, this large disk is toothed, so why do you need a flange? Why do flanges neλed teeth on them? Let me briefly say:

　　1. The flange is used to increase the force area of the nut and receivi↑ng surface. We all know that under constant pressure, the larger the force area, the sma​ller the pressure on the force surface, and the greater the ₽stress on the longitudinal and transverse nuts. This not only prevents damage caused by excessive ≈pressure on the flange nut contact surface, but also plays a role in preventing looseni↓ng and slipping.

　　2. The teeth on the flange surface of the flange nut enhance the anti looseni→ng effect of the flange nut, playing a certain anti vibration effect, so that the c∞onnection with the flange nut will not loosen during movement and high vibration, increasinεg safety and firmness.
