DIN 439 vs ISO 4035
Within this database the two standards list identical nominal dimensions for every overlapping size, so they are interchangeable for most purchasing purposes. Tolerances, marking requirements and material specifications are defined separately by each standard body and should still be checked.

Rows shaded amber differ between the two standards. Substitution should be checked against the affected sizes rather than assumed from the equivalence alone.
