Have you found a clean copy of the DIN 5482 1977 tables? Share your source (legally, please) in the comments. Engineers helping engineers is the only way we keep these standards alive.

A typical DIN 5482 designation looks like:

: Profile-centered (flank centering), meaning the connection is maintained by the contact between the tooth flanks. Reference System : Dimensions are often indexed by a nominal size

Includes uncommon sizes like 1.9, 2.1, and standard modules like 1.6 or 2.0

A 30° pressure angle offers a compromise between the 20° angle (better bending strength) and 45° angle (higher torque capacity). It reduces radial forces compared to 45° splines while maintaining a wider tooth base than 20° designs.
