Flange nuts are sometimes equipped with rotating flanges, which helps to form a more stable structure without affecting the finished product like serrated flange nuts. Rotating flange nuts are mainly used to connect wood and plastic. Sometimes both sides of the nut are serrated, allowing for locking on either side.
A flange nut is a type of nut that has a wide flange at one end and can be used as an integrated washer. This is used to distribute the pressure of the nut onto the fixed component, thereby reducing the possibility of component damage and making it less likely to loosen due to uneven fastening surfaces
