Hexagon Nut

Hexagon nut is used in conjunction with bolts and screws to connect the fastening mechanism. Among them, Type I hex nuts are the most widely used. Class C nuts are used on machines, equipment or structures with rough surface and low precision. Class A and Class B nuts are used for machines with smooth surface and high precision, equipment or structure. Type II hex nuts have a thicker thickness m and are often used in applications where assembly and disassembly are often required. The thickness m of the hexagonal thin nut is thin, and is often used when the surface space of the connected member is limited.
