  • Material: Carbon steel, which is relatively inexpensive and widely available. It offers good mechanical properties such as tensile strength and ductility. Common material grades include SAE 1006 to 1024 and AISI 1015 to 1045.
  • Performance Grade: Common grades include Class 4.8 and Class 8.8. For Class 4.8 bolts, the tensile strength is 400 MPa, and the yield strength is 320 MPa. For Class 8.8 bolts, the tensile strength is 800 MPa, and the yield strength is 640 MPa.
  • Head Style: Hexagonal head, which is a regular hexagon, providing a larger contact surface with the workpiece to distribute pressure evenly and prevent damage. It also allows for easy engagement with wrenches and sockets for convenient installation and removal.
  • Surface Treatment: Hot-dip galvanized, where the bolt is immersed in molten zinc to form a protective zinc coating. This enhances corrosion resistance, protects the bolt from rust and oxidation in various environments, prolongs its service life, and improves its appearance.
  • Dimensions: Available in various sizes, such as M5, M6, M8, M10, M12, M16, M20, M24, M30, M36, and more. Lengths vary depending on the diameter and application requirements. For example, M8 bolts can range from 12 mm to 150 mm or longer. The head width and thickness also differ, with specific dimensions defined by standards like DIN933.
  • Standards: Common standards include DIN933, DIN931, ISO 4017, ISO 4018, ASTM A307, and ASME B18.2.1. These standards specify the dimensions, performance requirements, and testing methods for bolts.
