The standard defines splines using a naming convention like:
: The official DIN 5464:2010-03 page for digital and print copies.
One of its most defining technical characteristics is that it specifies splines with a . This unique zero-degree flank angle means that the forces transmitted between the shaft and hub are purely tangential, preventing the hub from expanding due to radial force components—a crucial advantage for designs with thin hub walls or where precise centering is required. din 5464 standard pdf
Defines the physical profile of the splines for both the shaft and the hub.
The document is structured to cover the entire design and manufacturing process: The standard defines splines using a naming convention
: Many older DIN spline standards have been formally withdrawn or superseded by international standards like ISO 14 (Straight-sided splines for cylindrical shafts).

To ensure proper functionality, DIN 5464 specifies tolerances for both the shaft and the hub. The fits are generally chosen based on the required precision (sliding, transition, or interference fits).
The heavy series in DIN 5464 provides a to the standard spline profiles. While DIN ISO 14 (first published in 1986) defines the medium series for general-purpose applications, DIN 5464 was created for higher loads, with inspection procedures often based on the same principles for straightforward quality control.
Due to their robust design and resistance to radial deformation, these splines are prominently used across heavy industries:
