High Tensile Grade 8.8 Bolts are primarily crafted from medium carbon steel, which usually contains around 0.4% carbon and 0.4–0.6% manganese. They undergo a process of quenching and tempering to boost their strength. These bolts showcase a minimum tensile strength of 800 MPa and a yield strength of 640 MPa, providing excellent resistance to shear, stress, and deformation. With good hardness, impact toughness, and fatigue resistance, they are well-suited for high-load structural and mechanical applications. Their dependable mechanical properties ensure secure and long-lasting fastening in demanding environments.
