Crafted from medium carbon steel, our High Tensile Grade 4.8 Bolts are typically untreated or lightly heat-treated to achieve their impressive mechanical properties. They boast a tensile strength of around 400 MPa and a yield strength of about 320 MPa. While they may not match the strength of higher grades like 8.8 or 10.9, Grade 4.8 Bolts deliver ample strength for non-critical structural joints and light to medium-duty applications. They are known for their good ductility, making them easy to install, weld, and handle. To boost corrosion resistance in outdoor or humid environments, surface treatments like zinc plating or galvanizing can be applied.
