Manufacturer of High Tensile Grade 4.8 Hex Head Bolt and Class 4.8 Stud Bolts in India

The specification for Iso Class 4.8 standard covers Grade 4.8 fasteners like Bolts/Screws/Studs. This type of fastener Class 4.8 Bolt could either have Coarse thread and fine pitch thread formation. The standard Class 4.8 Carbon Steel Bolt has been manufactured from Low or medium carbon Alloy Steel. These steel grades are comparatively cheaper and less strong. In a partially or fully annealed condition, the tensile strength of the Grade 4.8 Nuts is around 420 Mpa for low carbon steel and 500 Mpa for medium carbon steel, its core hardness in terms of Rockwell lies between B71 – 95. The surface hardness of the Grade 4.8 Mild Steel Bolt can be increased through carburizing.

Although low and medium carbon steels have a low tensile strength, they are ductile. Hence they are easy to shape and are used in applications which tends to make the most of the ductile feature of the alloy. For instance, the Class 4.8 Material is used in mechanical equipment’s, buildings, bridges, tunnels, high speed railways etc. The size range of the Grade 4.8 Screw in a fully or partially annealed condition is between M5 to M100. While the 4.8 Grade Steel Bolt is available in self finished colour, other finishes applied to the steel alloy in order to provide additive value in terms of enhancing the physical or mechanical properties like its corrosion resistance and strength. Using Zinc either in the form of hot dip galvanization or for plating with white/ blue /yellow passivation increases the corrosion resistance of the Grade 4.8 Bolts. Other finishes used on the Class 4.8 Screw include blackened, nickel plated, cadmium plated and chromium plated.
