Foreword This standard h
3、as been prepared by Technical Committee Gewinde of the Normenausschu Technische Grundlagen (Fundamentals in Technology Standards Committee). 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
4、ndards, The nominal sizes are now based both on the basic dimensions specified in DIN IS0 724 and on the nominal profiles specified in DIN 13-19. 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
5、gnation is to be found in DIN IS0 965-1. See the table in the Explanatory notes of DIN 13-1 for an overview of DIN and DIN IS0 Standards for screw threads. Amendments This standard differs from the December 1986 edition in that the nominal sizes are now to be calculated on the basis of DIN 13-1 9 an
