What is a hexagonal nut

The use of hexagonal nuts in conjunction with screws, bolts, and screws serves to connect and tighten mechanical components. Among them, Type 1 six purpose nuts are the most widely used, while Class C nuts are used on machines, equipment, or structures with relatively rough surfaces and low precision requirements; A-grade and B-grade nuts are used on machines, equipment, or structures with relatively smooth surfaces and high precision requirements. The thickness M of type 2 hexagonal nuts is relatively thick, and they are often used in situations that require frequent assembly and disassembly. The thickness M of hexagonal thin nuts is relatively thin and is often used in situations where the surface space of the connected components is limited.
