The High Tensile 10.9 Screw is produced by use of medium carbon steel, a medium alloy of carbon steel and low carbon boron steel. These products are first quenched and tempered to ensure the best services. Due to their properties, they are used in industries of an automobile for the purpose of bolting large mechanical parts and also for forging metric parts. They are used in other industries as well because they have the good tensile strength and yield better results. Screws of this grade are also good in wear resistance and work well in extreme temperature conditions.
