Hexagon nuts are divided into three types according to their nominal thickness: type I, type II and thin type. There are two types of nuts above grade 8: Type 1 and Type II. Type I hex nuts are the most widely used. Type 1 nuts are divided into three grades: A, B and C. Among them, A and B nuts are suitable for machinery, equipment and structures with small surface roughness and high precision requirements. Grade C nuts are used for machines, equipment or structures with rough surfaces and low precision requirements; Type 2 hexagon nuts have a thicker thickness and are usually used in occasions that require assembly and disassembly.
There are usually two types, one is iron, or carbon steel. One is stainless steel, of course there are copper and aluminum nuts, but they are used less. Copper is still useful, while aluminum nuts are rarely used.
