If you write "±0.05" next to a dimension, that specific value overrides the general ISO 2768-mK class for that feature.
: Represents the K tolerance class for geometrical features (flatness, straightness, perpendicularity, symmetry). ISO 2768-1: Linear Dimensions (Class m) general tolerance iso 2768-mk
This report outlines the application and specifications of the general tolerance standard, which is widely used in mechanical engineering to simplify technical drawings by providing standard tolerances for dimensions and geometric features that do not have individual callouts. 1. Scope and Application If you write "±0
For parallelism , the tolerance equals the value of the size tolerance. For positional tolerances , the standard recommends using ISO 2768-2 only for "non-functional" features; otherwise, individually specify. general tolerance iso 2768-mk
