You might ask: "Can't I just open the old DIN 5482 handbook?" din 5482 spline dimensions calculator

In theory, yes. But in practice:

For DIN 5482 | External Spline | m=0.5 | z=36 | α=30° | Fit f5 Choose "Straight-sided spline" from the type menu

| Parameter | Symbol | Value (mm) | | :--- | :--- | :--- | | Reference diameter | d | 18.000 | | Base diameter | d(b) | 15.588 | | Major diameter (max) | d(ee max) | 18.675 | | Major diameter (min) | d(ee min) | 18.650 | | Minor diameter | d(ii) | 17.175 | | Tooth thickness max | s(max) | 0.798 | | Tooth thickness min | s(min) | 0.771 | | Recommended pin diameter | D(pin) | 0.900 | | Measurement over pins max | M(max) | 19.245 | | Measurement over pins min | M(_min) | 19.187 | DIN 5482 specifies involute splines with 30° pressure

DIN 5482 specifies involute splines with 30° pressure angle and flat root geometry, primarily used for automotive, hydraulic, and machine tool connections. Unlike DIN 5480 (30°–37.5° PA), DIN 5482 uses module series and distinguishes between light, medium, and heavy duty fits.
