Hex Bolt Manufacturers introduces the classification of hexagon nuts:
1. According to the nominal thickness, the hexagonal nuts are divided into three types: I type, II type, and thin type. Nuts above grade 8 are divided into two types: Type I and Type II. Type I hexagon nuts are the most widely used. Type 1 nuts are divided into three levels: A, B, and C. Among them, A and B nuts are suitable for machines, 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 II hexagon nuts have a thicker thickness and are mostly used on occasions where assembly and disassembly are often required. Type I nuts refer to ordinary hexagon nuts with a nominal nut height of m≥0.8D, and their type and size should meet the requirements of GB/T6170; while the height of type II nuts is higher than that of type 1 nuts, and their type and size should conform to GB/T6170. T6175. There are two purposes for adding type II nuts: one is to obtain a relatively inexpensive nut that does not require heat treatment by increasing the height of the nut.
2. Classified by tooth distance: standard teeth, regular teeth, fine teeth, very fine teeth, and reverse teeth.
3. Classified by material: stainless steel hexagonal nuts, carbon steel hexagonal nuts, copper hexagonal nuts, iron hexagonal nuts.
4. Classified by thickness: hexagonal thick nuts and hexagonal thin nuts.
5. Classification according to the method of use: hot-melt copper nuts, hot-pressed copper nuts, embedded copper nuts, and ultrasonic copper nuts.
Through the above introduction, Stud Bolt Supplier hopes that you can simply refer to the content of this article in future use.
