Hex nuts are commonly used in our daily lives, serving to provide a fixed function. There are many shapes and types of nuts available, among them the hex nut, also known as a hex cap nut. Different types of nuts include hexagon, circular, square, and others.
There are many standards for nuts, most of which are well-defined. Size standards, material requirements, electroplating standards and others are all clearly established. However, different types of nuts have different standards. This article will provide a detailed introduction to the specifications and standards of nuts. Hex nuts are used in conjunction with screws, bolts, and studs to connect fasteners. Grade C nuts are used on machines, equipment or structures with rough surfaces and low precision requirements. Grade A and B nuts can be used on machines, equipment or structures with smooth surfaces and high precision requirements.
Type II hex nuts are thick and are often used when disassembly is required. Thin hex nuts, with thickness M, are commonly used in restricted spaces on the surfaces of components. Hex nuts can be classified into three types according to nominal thickness: Type I, Type II, and Thin Type. Nuts with a grade of 8 or higher can be classified as Type I or Type II.
Type I hex nuts are more commonly used, and there are also classifications within Type I nuts. Grade A and B nuts can be used on machines, equipment, and structures with small surface roughness and high precision requirements. However, Grade C nuts are used on machines, equipment or structures with rough surfaces and low precision requirements. Usually, it is necessary to distinguish between fine-threaded and coarse-threaded nuts. However, regardless of the thread type, the specifications are the same, including M3, M4, M5, M6, M8, M10, etc. There are also hex nuts with English or American standards, reflecting only national standards. Hex nuts produced in China are referred to as national standard hex nuts.
This is the definition and classification of hex nuts. Do you understand it now? There are still many manufacturers of hex nuts in the market. We believe that Ningbo Datian Fasteners Co., Ltd. can provide you with the ideal hex nut!
