Using data from Table 2 of the PDF:
Unlike the more common medium series (DIN 5463), the heavy series defined in DIN 5464 is engineered for fixed or moving shaft-hub connections that face extreme mechanical stress. Key Technical Features 0° Flank Angle
The comprehensive provides localized geometric parameters vital to setting up automated cutting paths, broaching tools, and quality management gauges. din 5464 standard pdf

: Many older DIN spline standards have been formally withdrawn or superseded by international standards like ISO 14 (Straight-sided splines for cylindrical shafts). Using data from Table 2 of the PDF:
Using the DIN 5464 standard PDF offers several advantages, including:
Initial searches might incorrectly connect DIN 5464 to topics like nuts (DIN 6923) or aerospace parts (DIN 65246). DIN 5464 is exclusively about straight-sided splines . It can be purchased and downloaded as a
: One of the most significant advantages of this standard is the 0° flank angle. This design prevents the hub from expanding due to radial components of flank forces, which is essential for maintaining integrity in thin-walled hubs. Flank Centering

Below is a developed blog post centered around this standard, its applications, and how to access the official documentation.
The spline flanks feature a flat, straight profile perpendicular to the pitch circle. This design ensures that mating forces push purely tangentially, altogether preventing the hub from expanding outwards due to radial forces.
