For the production of precision ball screws, steels of the quality ČSN 14 260, CF53 or 42CrMo4 (shafts) and 14 109 or 14 209 (nuts) are used. The nuts and the threaded part of the spindle are case-hardened and reach a hardness of 58-60 HRC. The core and non-hardened parts of the shaft have a minimum strength of Rm = 650 MPa.
