Design analysis: The art of cylindrical heads
Cylindrical head, as the head design of the bolt, its shape is not random. With its round and smooth lines, it not only reduces the damage to the surrounding materials during installation, but also ensures the uniform distribution of bolts when stressed, effectively preventing the risk of fracture caused by stress concentration. In addition, the cylindrical head design is also easy to hide, in many occasions that need to keep the appearance clean, such as electronic equipment, precision instruments inside, it can be perfectly integrated, without destroying the overall beauty.
The wisdom of the hex
Compared with the traditional word or cross notch, the hex design is undoubtedly the embodiment of scientific and technological progress. It provides a larger torque transfer area, making it easier to tighten or loosen bolts and less prone to slippage. More importantly, this design can effectively prevent damage to the bolt head, even in the case of frequent disassembly, but also maintain high durability. For occasions requiring high strength fastening, such as automotive engines, heavy machinery, etc., hex bolts are undoubtedly the first choice.
Blue and white zinc plating: the art of preservation
In humid, corrosive environments, the durability of metal components is a major challenge. The surface treatment process of "blue and white zinc plating" covers the cylindrical head hex bolts with a protective coat. The blue and white zinc layer is not only beautiful, but more importantly, it can effectively isolate the erosion of air, moisture and chemical substances, and extend the service life of the bolt. At the same time, the coating also has good electrical conductivity and weldability, which provides convenience for subsequent processing and assembly.
Extended design considerations
The word "lengthening" seems simple, but it actually contains the thoughtful consideration of engineers. In some special application scenarios, such as the need to penetrate multiple layers of material or to reach a specific depth of connection points, ordinary length bolts are often inadequate. At this time, the extension bolt came into being. It not only solves the connection problem, but also improves the stability and reliability of the connection by increasing the embedding depth of the bolt. In addition, the lengthening design also provides the possibility to adjust the installation gap and compensate for manufacturing errors.
Application example: Witness the power
In the connection of the tower cylinder of wind turbine, the cylindrical head hexagonal hexagonal blue and white zinc plated lengthened triple bolt combination with its excellent performance ensures the stability and safety of the tower cylinder structure. In the connection between the car body and the bogie of the high-speed train, these bolts guarantee the smooth running of the train with their high precision and high reliability. In the aerospace field, it has become an important link connecting various parts of the aircraft, bearing huge loads and extreme environmental tests.
