The flange surface of the flange nut has grooves, which not only increases the contact area, but also has the effect of preventing looseness. It is common on the rotating mechanism.

Flange Bolt Manufacturers are sometimes electroplated to meet the color requirements proposed by customers. Electroplating can also be classified into environmental protection and non environmental protection. There are many types of electroplating, such as more expensive environment-friendly nickel, environment-friendly blue zinc, environment-friendly black zinc, environment-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.

Hexagon nuts are used together with bolts and screws to connect and fasten parts. Among them, Type 1 six purpose nuts are widely used in Z, and Grade C nuts are used in machines, equipment or structures with rough surfaces and low precision requirements; Class A and B nuts are used on machines, equipment or structures with smooth surfaces and high requirements for accuracy. The thickness M of type 2 Custom Flange Bolt is relatively thick, which is usually used in the occasion where assembly and disassembly are often required. The thickness M of the hexagon thin nut is relatively thin, which is mainly used in the occasion where the surface space of the connected parts is limited.
