⚠️ These are general linear tolerances. For functional features (e.g., fits with metal parts), tighter TG3 or TG4 is recommended.
The following table highlights how TG5 sits within the hierarchy of DIN 16742: Tolerance Group Production Type Typical Usage/Requirements din 16742 - tg5

The standard strictly defines surface roughness based on comparator blocks. TG5 requires surfaces to be free from visible sink marks, flow lines, and ejector pin marks that exceed a depth of 0.02 mm. It aligns roughly with Rz 10–20 µm (average maximum height of the profile). fits with metal parts)
