If you work in mechanical engineering, automotive drivetrain design, or precision machining, you’ve likely encountered the DIN 5480 standard. It is the go-to specification for involute splines based on reference diameters, used heavily in Germany and across Europe.
DIN 5480 is a German standard for splines, which are used to transmit rotational motion and torque between two shafts. Here is a helpful feature to extract and summarize the key dimensions for DIN 5480 spline: din 5480 spline dimensions pdf
