1、DEUTSCHE NORM November 1999 General purpose IS0 metric screw threads Part 4: Nominal sizes for 0,751 mm fine pitch threads with diameters from 5 mm to 11 O mm DIN - 13-4 ICs 21.040.10 Supersedes December 1986 edition.

2、Steigung 0,75 mm - Gewinde-Nenndurchmesser von 5 mm bis 110 mm In keeping with current practice in standards published by the International Organization for Standardization (ISO), a comma has been used throughout as the decimal marker. Foreword This standard has been prepared by Technical Committee
3、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 standards, The nominal sizes are now based
4、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 designation is to be found in DIN IS0 965-1.
5、 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 and size 7 mm threads have been assigned t
6、o series 2 (cf. table 1). Previo us edit ions DIN 13-35: 1961 -01,1962-1 O, 1964-06; DIN 51 8: 1923-1 O, 1943-09,1952-12; DIN 13-4: 1970-04, 1986-1 2. All dimensions are in mm. 1 Scope This standard applies to general purpose IS0 metric screw threads. It specifies the nominal sizes for 0,75 mm fine
7、pitch threads with diameters from 5 mm to 11 O mm having the basic profile specified in DIN ISO68-1 and the nominal profile specified in DIN 13-19. 2 Normative references This standard incorporates, by dated or undated reference, provisions from other publications.
