To obtain an official, accurate, and legal copy of the DIN 5464 standard PDF, engineers and purchasing departments should use licensed distributors:

: Typically 10 or 20 splines, depending on the diameter.

Because the standard relies heavily on for the fundamental inspection and gauging methods, those procedures are not repeated in DIN 5464; they are implicitly valid and are not additionally listed.

standard, titled "Straight-sided splines – Heavy series," is a technical specification published by the German Institute for Standardization (DIN) that defines the geometry, dimensions, and tolerances for heavy-duty splined shaft and hub connections.

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.
