4 Limits of size
The limits of size for fine pitch threads with preferred tolerance classes (cf. DIN ISO 965-1) have been calculated on the basis of the nominal dimensions as in DIN 13-5 to DIN 13-11, applying the limit deviations and tolerances as in DIN ISO 965-1. Limits of size for threads with tolerance classes not covered in this standard may be calculated using the limit deviations as in DIN ISO 965-3.
The limits for the root radius of the external thread are specified in DIN ISO 965-1 as R = 0,144 34 P = H/6 for the maximum limit of size and R min = 0,125 P ≈ H/7 for the minimum limit of size of the minor diameter d 3 .DIN 13-24 pdf download.
