You can purchase and download the official PDF from several accredited standards distributors:
A details precise dimensional tables categorized by the nominal dimensions of the shaft and hub. The primary parameters tracked in these tables include: Number of Teeth ( ) : The exact spline count for the heavy series profile. Minor Diameter ( ) : The inner base diameter of the spline shaft. Major Diameter ( ) : The outermost tip-to-tip diameter of the spline shaft. Spline Width ( ) : The thickness of each straight-sided key flank. Typical DIN 5464 Size Profiles (Example Dataset)
The standard defines splines using a naming convention like: din 5464 standard pdf

While many third-party engineering blogs offer summarized dimension charts, the official, legally binding must be purchased through authorized distributors such as Beuth Verlag or the ISO Store. Utilizing unauthorized or outdated PDFs from unverified sources can result in using obsolete tolerances, causing structural failures or mating components that do not fit.

Always verify you have the latest revision and any related amendments or cross-referenced standards.
If you are working on a specific design project, let me know: What are your requirements? What torque loads will the joint experience? Major Diameter ( ) : The outermost tip-to-tip
If you are working on a specific mechanical design, let me know:
Pressure Angle: The parallel flanks transfer torque perpendicular to the faces. Because the flank force features a zero-degree angle, it lacks a radial splitting component.
is a German industrial standard (Deutsches Institut für Normung) that specifies involute splines for internal and external gear teeth with a module of 0.6 to 10. More specifically, it covers side-fit splines where the centering is achieved by the flanks of the teeth.
