12、L STANDARD JIS B 0209-3 : 2001 (IS0 965-3 1998) IS0 general purpose metric screw threads - Tolerances - Part 3: Deviations for constructional screw threads Introduction This Japanese Industrial Standard has been prepared based on the third edition of IS0 965-3 IS0 general purpose metric screw thread
13、s-Tolerances- Part 3: Deviations for constructional screw threads published in 1998 without modifying the technical contents. 1 Scope This Standard specifies deviations for pitch and crest diameters for IS0 general purpose metric screw threads (M) conforming to JIS B 0205-2 having basic profile acco
14、rding to JIS B 0205-1. The deviations specified are derived from the fundamental deviations and tolerances specified in JIS B 0209-1. Remarks: The International Standard corresponding to this Standard is as follows. In addition, symbols which denote the degree of correspondence in the contents betwe
15、en the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21.
