To obtain the official , purchase it from an authorised distributor such as DIN Media , Normadoc , or Standards.ie . Always select the correct language edition and be aware of the standard’s withdrawal status before using it for a new project.
The standard provides a dimensional matrix based on the number of teeth ( ) and the nominal diameter ( ). Parameter Description Typically 8, 10, or 20, depending on the shaft size. Minor Diameter ( ) The inner diameter where centering usually occurs. Major Diameter ( ) The outer diameter of the spline teeth. Width of Key ( ) The thickness of the individual spline teeth.

The standard has evolved over several decades:
: By focusing on the "heavy series" geometry, DIN 5464 maximizes the surface area available for load distribution, making it the go-to for industrial machinery and heavy automotive drivetrains. Why Use DIN 5464?
Not directly. ISO 4156 covers involute splines but is based on a different system (reference diameter, module, and pressure angle). Always check compatibility. To obtain the official , purchase it from
The is an indispensable tool for any mechanical engineer dealing with splined shaft connections. While the temptation to find a free PDF is understandable, the safe, legal, and accurate route is to purchase the current version from DIN Media or a national standards body.
For a module (m) of 5 mm with 30 teeth:
Where high torque and precision alignment are essential. Parameter Description Typically 8, 10, or 20, depending
is a German standard developed by the Deutsches Institut für Normung (DIN) that specifies requirements for straight‑sided splines with a 0° pressure angle , particularly the heavy series for fixed and moving shaft‑hub connections. Straight‑sided splines are designed to transmit high torques while keeping the hub wall thickness low.
