Nonferrous EN 14399-4-2015 High-strength structural bolting assemblies for preloading-system HV
Product details
High-strength structural bolting assemblies for preloading - system HV is a fastener specifically designed for high load and preload requirements. The bolt thread specifications range from M12 to M36, with a pitch varying from 1.75mm to 4mm. The product grade is Class C. In order to improve the corrosion resistance and service life of the bolt, the product is usually surface treated. Common surface treatment methods include hot dip zinc, blue and white zinc, black and so on. These treatments can form a protective film on the bolt surface to protect it from oxidation and corrosion. The bolts made of non-ferrous metals such as copper and aluminum are often used in occasions with high requirements for strength and corrosion resistance.
Product Characteristics
- High strength: the bolt is made of high strength alloy steel, and after heat treatment and other processes, it has high tensile strength and yield strength, and can withstand large preload and working load.
- High accuracy: the dimensions, tolerances and fit accuracy of the bolts meet the requirements of EN 14399-4, ensuring interchangeability and assembly performance with the matching nuts and washers.
- Large hexagonal head design: The head of the bolt adopts a large hexagonal design, which is easy to use tools such as wrenches to tighten the operation and improve work efficiency.
- HV system: As part of the HV system, the bolts work together with the corresponding nuts and washers to form a complete connection system to ensure the stability and safety of the connection.
Application
- Building steel structure: such as large Bridges, high-rise buildings, stadiums and other building structure connection and fixing.
- Machinery and equipment: It plays an important role in the structural connection of heavy machinery, wind power equipment, petrochemical equipment and other fields.
- Infrastructure: In the construction and maintenance of infrastructure such as railways, roads and ports, it is used to connect and strengthen key structures.
