For the class, these values are halved. For the Coarse class, they are doubled.
Let’s look at a practical example to interpret the data.
There is no standalone modern article just on because it is obsolete. For a detailed read, search for "ISO 2768-1 general tolerances" – every value and rule in that standard is directly derived from DIN 7160. Any article covering "General tolerance ISO 2768-1" will give you 100% of the information you need about DIN 7160. din 7160 tolerance
While the standard covers a vast
A shaft has a nominal diameter of 25 mm and a tolerance specification of h6 . For the class, these values are halved
DIN 7160 assumes cylindrical clearance holes. For threaded holes, the fastener alignment depends on the thread tolerance, not the center distance tolerance. Use a different strategy (e.g., floating nut plates).
Alternatively, for a specific dimension: There is no standalone modern article just on
Unlike general dimension tolerances (like DIN ISO 2768), DIN 7160 acknowledges that center distances have a non-linear relationship with assembly functionality. Specifically, the standard is built for where a single bolt or pin must pass through two components.
If you want to invoke DIN 7160 on a technical drawing, you should add a note in the title block or general tolerance block:
