The standard defines the geometry using the following key terms:
Ensure both parts share the same root style. Forcing a flat-root shaft into a fillet-root hub can result in structural binding or premature component failure.
Used strictly when high-precision coaxial alignment is mandatory. Verifying PDF Data and Tolerances

Standardized classes include 7H, 9H, and 11H. The standard defines the geometry using the following
The standard is split into several parts, but the core dimensional data is governed by:
For standard configurations, the relationship between reference diameter and module determines the tooth count:
Root Diameter (df1)=m×(z−1.2)Root Diameter open paren d sub f 1 end-sub close paren equals m cross open paren z minus 1.2 close paren Verifying PDF Data and Tolerances If you can
Example: DIN 5480 – W 45 x 2 x 24 x 9H
To ensure you are using the latest, verified data (including 2006-2010 revisions), you should look for the following reputable sources:
Don't trust every random download. Verify your dimensions against these criteria:
d_ref = z * m
