Types and weight standards of hex nuts

Hexagon nuts are used in conjunction with bolts and screws to connect and tighten parts. Among them, type 1 six-purpose nuts are the most widely used. Grade C nuts are used for machines, equipment or structures with rough surfaces and low precision requirements; Grade A and B nuts are used for smoother surfaces and higher precision requirements. On the machine, equipment or structure. The thickness M of the type 2 hex nut is relatively thick, and it is mostly used in occasions that often require assembly and disassembly. The thickness M of the hexagonal thin nut is thin, and it is mostly used in occasions where the surface space of the connected parts is restricted.
