Product Characteristics
Application
Product Characteristics
- Larger series: Compared to ordinary hexagon head flange bolts, GB/T 5789-1986 larger series has a larger opposite side width and flange diameter, providing higher load capacity and better fastening effect.
- Hexagonal head: The head is designed with a hexagonal shape, which is easy to use tools such as wrenches and screwdrivers to tighten and disassemble, improving work efficiency.
- Flange structure: the bolt head has a flange surface, which increases the contact area with the connector and improves the stability and sealing of the connection.
Application
- Automobile manufacturing: The connection and fixing of automobile body, engine, chassis and other parts require bolts with high strength and durability.
- Shipbuilding: The connection and fixing of hull structure, deck, mechanical equipment, etc., need to withstand the corrosion of seawater and the impact of large wind waves.
- Mechanical manufacturing: The connection and fixing of various mechanical equipment, such as engines, transmissions, transmission shafts, etc., require bolts with high precision and reliability.
