Application
Product Characteristics
- High strength and preload adaptability: The bolt and nut connection pairs under this standard are designed to withstand high preloads and are primarily extended by the plastic extension of the bolt, thus ensuring the reliability and stability of the connection.
- 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 improves the construction efficiency.
- Strict quality control: Products are manufactured and inspected in accordance with strict national standards to ensure reliable product quality.
Application
- Industrial and Civil Buildings: It is suitable for steel structural components requiring high strength connection, such as beams, columns, joints, etc.
- Bridge and tower structure: In bridge, tower mast and other structures, the connection pair can provide a reliable pre-load connection to ensure the safety and stability of the structure.
- Boiler steel structure and lifting machinery: In heavy equipment such as boiler steel structure and lifting machinery, the connection pair can withstand large loads and vibrations to ensure the normal operation of the equipment.
