There are many types of bolts and nuts, and each type is suitable for different scenarios and has different characteristics. The following is an analysis of common bolts and nuts: Full thread bolts and nuts: Application scenario: Full thread bolts and nuts are suitable for scenarios that require high connection strength and tensile strength, such as steel structures, Bridges, and large machines. Features: Threaded bolts and nuts are threaded to cover the entire length, providing greater connection area and tensile properties, and uniform distribution of response forces. They are usually made of high-strength materials and are equipped with anti-loosening structures. Semi-threaded bolts and nuts: Application scenario: semi-threaded bolts and nuts are widely used in fastening connections in automotive, mechanical equipment, rail transit and other industries, and are also commonly used in home decoration, furniture production and other fields. Features: The threads of semi-threaded bolts and nuts occupy only part of the length, generally the end of the bolt. This design is more convenient during installation and replacement, and is suitable for frequent disassembly and loading and unloading. At the same time, the load of semi-threaded bolts and nuts is dispersed, which can reduce stress concentration. Round head bolts and nuts: Application scenario: Round head bolts and nuts are widely used in electronic equipment, home appliances, furniture, and other fields, as well as the need for high aesthetic connection. Features: The head of the round head bolt and nut is designed as a round, simple and beautiful shape. They are usually fastened using hex or flat head screw tools, and will not be prominent in appearance, and in some special decorative needs, round head bolts can provide better visual effects. Cone-head bolts and nuts: Application scenario: Cone-head bolts and nuts are mainly used for complex joints of machine tools, large equipment, and connections requiring high precision and stability. Features: The head of the taper bolt is a conical shape, and the taper is carefully controlled, which can provide better neutralization and positioning effect. The nut also matches, with the same taper. The combination of cone-head bolts and nuts ensures the stability and accuracy of the connection. The above is the application scenario and feature analysis of common types of bolts and nuts. Depending on the specific application requirements and design specifications, selecting the right bolt and nut type can provide a reliable fastening connection. In the selection and use, should also follow the relevant standards and specifications, and consider special requirements such as anti-loosening, anti-corrosion, etc.
