An 8.8 grade bolt is typically made from medium carbon steel, often alloyed with elements like manganese to enhance strength and hardness. The bolt is usually heat-treated to achieve the desired mechanical properties, providing a tensile strength of 800 MPa and a yield strength of 640 MPa. It may also have a surface finish for corrosion resistance, such as zinc plating.
