The adoption of a number of IS0 Standards (e.g. IS0 724, IS0 965 series) as national standards led the responsible committee to revise the DIN 13 series of sta

The nominal sizes of the external thread minor diameters specified here have been calculated taking the root radius as being equal to H/6. The thread desi
