carbon steel 12.9 full threaded stud bolt fasteners DIN975
Carbon steel nut and bolt grades are divided into three different categories based on the carbon content of mild, medium and high carbon steels. Mild steel hex bolts are the most widely used category of all carbon steel groups. Mild steel threaded bolt alloys typically contain less than 0.25% carbon by weight. Since this type of carbon steel bolt cannot be hardened by heat treatment to promote the formation of martensite, the alloy is cold worked.
