High Tensile Grade 4.8 Bolts are primarily made from medium carbon steel, typically featuring around 0.40% carbon, 0.70–0.90% manganese, along with trace amounts of sulfur and phosphorus. These bolts strike a great balance between strength and ductility. In terms of mechanics, they boast a tensile strength of 400 MPa and a yield strength of at least 320 MPa. Their moderate hardness makes them perfect for general engineering applications, providing a secure and stable fastening solution without sacrificing machinability or ease of installation.
