The short answer is . Withdrawn standards may in principle continue to be applied if this is agreed upon between contracting parties and not prohibited by law. However, for new product designs or modifications to existing equipment, engineers are strongly encouraged to transition to DIN ISO 14 or the international equivalent ISO 14 .

Unlike simple keyed shafts, splines are used when high torque needs to be transmitted and there is a requirement for relative axial movement (sliding) between the shaft and the hub. The "involute" profile—shaped similarly to gear teeth but with shorter heights—offers distinct mechanical advantages over straight-sided splines. The short answer is
Internal 4-spline bores are best produced using broaching tools or wire EDM for low-volume prototyping. | Number of Keys | Centering | Inside
