ISO 7043 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 12, Fasteners with metric internal thread . This third edition cancels and replaces the second edition (ISO 7043 :1997), of which it constitutes a minor revision.

ISO 7043:2012 specifies the characteristics of prevailing torque type hexagon nuts with flange (with non-metallic insert), of style 2, with threads from M5 to M20 inclusive, in product grade A for threads up to and including M16 and product grade B for threads above M16, and with property classes 8, 9 and 10.

① 本标准的螺母高度属于2型螺母，但 iso 2320对所有的性能等级和规格并非只规定2型螺母，在某些情况下，还需要按1型螺母进行试验。 引用参考 GB /T 1172
