1. 4.8 grade A3 Q235, Q195 and other low carbon steels. 2. Grade 5.8 ,material Q235 and above are acceptable, and no heat treatment is required.     3. Grade 8.8, thread diameter below 16MM, material 35 steel ,quenching and tempering heat treatment .Above 16mm, 45 steel and low carbon alloy steel are quenched and tempered.
