Recommendations for materials for the production of self-tapping screws

For the production of self-tapping screws, SAE 1022 or SAE 1018 wire is recommended. The numbers at the end of the markings 22 and 18 indicate the carbon content of the steel in hundredths. For large threading angles, a material with a higher carbon content is recommended.
