Carbon Steel ISO 4014-2022 Hexagon head bolts

The thread specifications of hexagon head bolts range from M1.6 to M64, with a pitch ranging from 0.35mm to 6mm. Hexagon head bolts in standards are typically categorized into Grade A and Grade B. The material is carbon steel. To enhance their corrosion resistance and aesthetics, surface treatments such as blue-white zinc plating are often applied.
 
Functional Characteristics

• Hexagonal head design: The head of the bolt is hexagonal, which is easy to tighten or remove with tools such as wrenches or pliers.
• Size standardization: According to ISO 4014, the dimensions of the bolts (such as diameter, length, thread, etc.) meet international standards, ensuring compatibility with the corresponding nut or hole.
• Reliable performance: The standard specifies the material, mechanical properties and test methods of the bolts to ensure that the bolts can meet the corresponding strength and reliability requirements during use.

 
Application
These bolts are widely used in industrial equipment, construction, automobiles, marine vessels, aerospace, and various other fields.

• Automotive : Used to connect engine, chassis and other components in the automotive manufacturing process.
• Construction: Used for the connection and fastening of steel structure buildings, such as Bridges, high-rise buildings, etc.
• Aerospace: Used in the aerospace industry to connect key parts such as aircraft structures and engine components.
