Stainless Steel GB/T 5790-1986 Large hexagon head flange bolts with reduces shank—Type A

Bolt thread specifications M5-M20, pitch range from 0.8mm to 2.5mm. The product grade is B, usually including carbon steel, alloy steel, etc. According to the use environment and requirements, the bolt surface can be galvanized, blackened, sprayed and other treatment to improve corrosion resistance and beauty. Widely used in machinery and equipment, bridge construction, automobile manufacturing, shipbuilding and other fields.
 
Product Characteristics

• Hexagonal flange design: The head design is hexagonal flange surface, easy to use tools such as wrenches to tighten operation, increase the stability and reliability of the connection.
• Thin rod structure: the bolt rod part is thin, suitable for limited space or need to reduce weight occasions.
• Larger series: Compared to the standard series, the bolt has a larger size and greater load capacity, and is suitable for connections that withstand large tensile forces and shear forces.

 
Application

• Mechanical equipment: widely used in the connection parts of various mechanical equipment, such as engines, transmissions, transmission devices, etc., to ensure the stability and safety of equipment operation.
• Bridge construction: In the connection of steel structures such as Bridges and buildings, the bolt can withstand large loads to ensure the stability and durability of the structure.
• Vehicles: In the manufacture and maintenance of vehicles such as cars, trains, ships, the bolt is often used for the connection of key parts to ensure the safe operation of vehicles.
• Other fields: It is also suitable for equipment connection in chemical, electric power, metallurgy and other industries to meet the needs of use in various harsh environments.
