The “Note“ underlined with dots is the matter not included in the original Inter- national standard. 1 Scope This Standard specifies the basic dimensions, in milimetres, of IS0 met- ric screw threads in accordance with JIS B 0205-2. The values refer to the basic profile in accordance with JIS B0205-1. Remarks: The International Standard corresponding to this Standard is as follows. In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21.
