High Strength Hexagon Bolts
High Strength Hexagon Bolts refer to bolts with a strength grade of 8.8 or higher, commonly using strength grades 8.8s and 10.9s, with 10.9s being the most prevalent. High Strength Hexagon Bolts require a large preload and are frequently used for connections in structures such as bridges, rails, and high-voltage and ultra-high-voltage equipment.
Description
High Strength Hexagon Bolts refer to bolts with a strength grade of 8.8 or higher, commonly using strength grades 8.8s and 10.9s, with 10.9s being the most prevalent. High Strength Hexagon Bolts require a large preload and are frequently used for connections in structures such as bridges, rails, and high-voltage and ultra-high-voltage equipment.
The smallest size for high strength hexagon bolt is M12, with M16 to M30 being commonly used. High strength hexagon bolt connections clamp the connecting plates together using a large preload within the bolt shank, generating significant friction to improve the overall integrity and rigidity of the connection. When subjected to shear force, depending on design and load requirements, they can be classified into friction-type high-strength bolt connections and bearing-type high-strength bolt connections.
Classification of High Strength Hexagon Bolts:
Friction-type high strength hexagon bolts: Suitable for beam and column connections in steel frame structures, solid-web beam connections, heavy-duty crane beam connections in industrial plants, braking systems, and connections in important structures subjected to dynamic loads.
Bearing-type high strength hexagon bolts: These can be used for shear connections in statically loaded structures or members indirectly subjected to dynamic loads where a small amount of slippage is permissible.
Tension-type high strength hexagon bolts: These bolts have lower fatigue strength under tension, and their load-bearing capacity under dynamic loads is unlikely to exceed 0.6P (where P is the bolt’s allowable axial force). Therefore, they are only suitable for use under static loads, such as flange connections and T-joints in compressed members.
High-strength hexagon bolts (including both external and internal hexagon types) are widely used in industrial and engineering applications where high connection strength and safety are critical due to their high strength and reliability. According to the latest publicly available information, their main applications are as follows:
Main Applications of High Strength Hexagon Bolts:
1. Steel Structure Connections: High strength hexagon bolts are used for friction-type or bearing-type high-strength bolt connections in steel structures such as bridges, towers, high-rise buildings, and hoisting machinery, ensuring structural stability under heavy loads.
2. Heavy Machinery Equipment: High strength hexagon bolts are used for fastening critical internal components in equipment such as construction machinery, mining equipment, and wind turbines, withstanding continuous vibration and impact loads.
3. Automotive and Rail Transportation: High strength hexagon bolts are used in critical components such as engines, chassis, and transmissions. Some vehicle models even use 12.9 grade high-strength bolts to enhance safety.
4. Power and Energy Facilities: High strength hexagon bolts are used in applications such as transmission towers, substation frames, and boiler steel structures, requiring corrosion resistance (often treated with hot-dip galvanizing or Dacromet coating).
5. Precision Equipment and Mold Fixing: Due to their countersunk design and compact structure, high strength hexagon bolts are commonly used in space-constrained applications such as the installation of precision instruments and molds.
