Below is an overview of its purpose, technical characteristics, and practical application. Purpose and Scope The primary function of DIN 5464 is to standardize straight-sided splines
Ensuring grinding wheels, milling cutters, and lathe chucks rotate with zero wobbling.
When checking the engineering details, you will find integrated fit clearances compiled directly from historic mechanical criteria—such as the integrated tolerance tables adopted from the withdrawn DIN 5465 framework . Procurement and Implementation
). The flanks of the teeth primarily serve to transmit torque, while the minor diameter controls the radial runout and axial alignment. Key Applications din 5464 standard pdf
Used in power transmission where high torque needs to be transmitted through a shaft to a gear, pulley, or coupling. Where to Obtain the PDF
The DIN 5464 standard is a German national standard that specifies the dimensions, tolerances, and requirements for splined hubs and spline shafts. The standard is published by the Deutsches Institut für Normung (DIN), which is the German national standards organization.
Typically flank-centered, though additional diameter centering can be defined. Below is an overview of its purpose, technical
: Primarily flank-centered, though diameter centering is possible.
The DIN 5464 standard is a cornerstone of German and international mechanical engineering, providing the necessary specifications for creating robust, high-capacity shaft-hub connections. By defining the precise geometry and tolerances of straight-sided splines in a "heavy series," it enables engineers to confidently design and manufacture components capable of transmitting very high torques within compact, lightweight assemblies. To legally and reliably implement these designs, obtaining a copy of the current from an authorized standards reseller is a vital and necessary step for any professional looking to ensure the quality, safety, and performance of their mechanical systems.
This indicates a heavy-series spline shaft built according to DIN 5464 containing , a 36 mm minor diameter , and a 45 mm major diameter . The matching hub uses corresponding internal ISO tolerances (such as H7, H12, or D10) depending on whether a sliding, transition, or interference fit is required.

The standard, officially titled "Hexagon nuts with metric fine pitch thread with flange – High strength" (or equivalent depending on the language edition), specifies the properties of hexagon flange nuts with a fine pitch thread.
Establishes the boundaries for heavy-series straight-sided profiles.
