11、Introduction This Japanese Industrial Standard has been prepared based on IS0 7042 Prevailing torque type all-metal hexagon nuts, style 2-Property classes 5, 8, 10 and 12, IS0 7719 Prevailing torque type all-metal hexagon nuts, style 1-Prop- erty classes 5, 8 and 10 and IS0 7720 Prevailing torque ty
12、pe all-metal hexagon nuts style 2-Property class 9 published in 1997 as second editions, and IS0 10513 Pre- vailing torque type all-metal hexagon nuts, style 2, with metric fine pitch thread- Property classes 8, 10 and 12 published in 1997 as the first edition, without modifying the corresponding pa
13、rts (shape, dimensions, and specification and designation of products) being compiled and integrated. In addition, JIS B 1199 specifying prevailing torque type nut products consists of four parts. The relation between each part and the International Standards cor- responding thereto is shown in Anne
14、x 1 (informative). 1 Scope This Standard specifies the characteristics of prevailing torque type all- metal hexagon nuts for general use. If other specifications are required, they should be selected from existing stan- dards, for example JIS B 0205, JIS B 0207, JIS B 0209, JIS 3 0211 and JIS B 1056
15、. The International Standards corresponding to this Standard are 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) ac- cording to ISO/IEC Guide 2
