17、2012(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for whi
18、ch a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all m
19、atters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circu
20、lated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsib
21、le for identifying any or all such patent rights.ISO 10512 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 12, Fasteners with metric internal thread.This second edition cancels and replaces the first edition (ISO 10512:1997), of which it constitutes a minor revision.iv ISO 2

23、pe hexagon regular nuts (with non-metallic insert) with metric fine pitch thread with nominal thread diameters, D, from 8 mm up to and including 36 mm, in product grade A for sizes D up to and including 16 mm and product grade B for sizes D above 16 mm, and with property classes 6, 8 and 10.If other
24、 specifications are required, they can be selected from existing International Standards, for example ISO 261, ISO 724, ISO 898-2, ISO 965-2, ISO 2320 and ISO 4759-1.NOTE 1 The dimensions of the nuts correspond to those given in ISO 8673 plus prevailing torque feature.NOTE 2 As there is an insuffici
25、ent nut height due to the fine pitch thread, there is a higher probability of nut thread stripping. Hence, high nuts according to ISO 7041 are preferably used.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable to its
