    Description

    Sign

    High strength hexagonal bolts usually refer to bolts with a grade of 8.8 or above, which have high tensile and yield strength, and are therefore called high-strength. The grade strength of hexagonal bolts can reach 12.9, and the material is mostly carbon steel, which is iron. This type of bolt, due to its unique hexagonal head and threaded design, can provide greater clamping force and better stability in fasteners. There are strict standards and regulations for the hardness, performance requirements, and usage of high-strength hexagonal bolts to ensure their safety and reliability in various application scenarios.

     

    Hardness and performance requirements: The tensile strength of high-strength hexagonal bolts can reach 400MPa level, and the nominal yield strength can reach 240MPa level. For high-strength hexagon socket head screws with a performance level of 10.9, the nominal tensile strength of the material is 1000 MPa and the nominal yield strength is 900 MPa. These bolts usually adopt internationally recognized standards to ensure consistent performance under different materials and conditions.

    Purpose: High strength hexagonal bolts are widely used in various working environments that require heavy loads and vibrations due to their high strength and stability, such as connecting machine tools and their accessories. The head design of these bolts ensures that the surface of the workpiece remains flat and aesthetically pleasing during installation. Additionally, due to their unique head design, specialized hex wrenches are required for installation and disassembly, which may cause inconvenience in situations where frequent disassembly is necessary, but on the other hand, it guarantees safety during use.

    Material and grade: High strength hexagonal bolts come in various materials, including stainless steel, carbon steel, alloy steel, etc. Common grades include 4.8, 8.8, 10.9, and 12.9, with bolts above 8.8 being considered high-strength bolts. The standards and specifications of these bolts follow the national standard GB70-1985, providing multiple specifications to meet different application needs.

     

    The standards for high-strength hexagonal bolts mainly include material, performance grade, size specifications, and other aspects. ‌

    Material: High strength hexagonal bolts are usually made of materials such as stainless steel, carbon steel, and alloy steel. These materials have good mechanical properties and can meet the requirements of high-strength applications.

    Performance level: The performance level of high-strength hexagonal bolts is usually 8.8 or above, including 8.8, 10.9, 12.9, etc. These grades are classified based on the tensile strength and yield strength of bolts, with grade 12.9 bolts having extremely high strength and hardness, suitable for critical connection parts such as mechanical structures with high strength requirements in aerospace, automotive engines, etc.

    Size specifications: There are various sizes of high-strength hexagonal bolts, including M1.6 to M6. Specific specifications such as M1.6 hexagon socket bolts have clear standards for head diameter, thickness, dimensions of the opposite sides of the hexagon socket, thread length, etc. As the diameter of bolts increases, such as M2, M2.5, M3, M4, M5, M6, etc., their size specifications will also increase accordingly to meet the needs of different application scenarios.

    Application scenarios: High strength hexagonal bolts are suitable for applications that can withstand large loads and harsh environments, such as heavy machinery, pressure vessels, and special equipment. Choosing the appropriate hexagon socket bolt requires consideration of its strength grade, material characteristics, and application environment to ensure the reliability and safety of the connection.

    In summary, the standards for high-strength hexagonal bolts cover multiple aspects such as material, performance grade, and size specifications, ensuring their reliability and safety in various high-strength application scenarios

    High strength hexagonal bolts are mainly used in applications with high mechanical performance requirements, such as injection molding machinery, hydraulic equipment, mold assembly, gearboxes, bearing seats, etc. These bolts, due to their high strength and durability, can meet the critical connection requirements of various mechanical equipment. In addition, they are also used in the field of construction and decoration to fix various materials such as boards and pipes, as well as in the field of automotive maintenance to fasten body parts, engine components, etc.

    The strength grade of high-strength hexagonal bolts is usually 12.9, which means that their surface hardness after heat treatment can reach 39-44 degrees, with a minimum tensile strength of 1220 Mpa and a hardness of 39-44 HRC. This type of screw is usually made of stainless steel, carbon steel, or alloy steel, ensuring its excellent mechanical properties.
