There are grooves on the flange surface of the flange nut, which not only increases the contact area, but also prevents loosening, which is common on rotating mechanisms.

Flange Nuts Suppliers sometimes also perform electroplating treatment to meet the desired color proposed by customers. Electroplating is also divided into environmental protection and non-environmental protection. There are many types of electroplating, such as more expensive environmentally friendly nickel, environmentally friendly blue zinc, environmentally friendly black zinc, environmentally friendly color zinc, etc. Of course, there are also cheaper ordinary electroplating, such as white nickel, white zinc, color zinc, black zinc, etc. In a word, environmental protection is more expensive than non-environmental protection.

The surface contact area between the flange nut and the connecting piece is large, which determines its use. When two parts connected by bolts and nuts are connected by bolts and nuts, for the convenience of connection, the bolt hole of one part is usually processed very large. The timing will be very convenient. The two holes do not need to be aligned very accurately to realize the bolt connection. If the bolt hole is enlarged, the contact area between the ordinary nut and the connected part will inevitably be reduced, so this kind of flange nut is used. This can be avoided. Generally, there are more flange nuts for steel structures.
