8、rd IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technic
9、al committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with 60, also take part in the work. IS0 collaborates closely with the international Electrotechnical Commission (IEC) on all matters of ele
10、ctrotechnical standardization. Draf International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 YO of the member bodies casting a vote. International Standard IS0 262 was prepare

This second edition cancels and replaces the first edition (IS0 262:1973) which has been technically revised. 1 Scope This International Standard specifies selected sizes for screws, bolts and nuts in the diameter range
12、 from 1 mm to 64 mm of IS0 general purpose metric screw threads (M) having basic profile according to IS0 68-1. These selected sizes are recommended also for general engineering use. These screw threads are selected from IS0 261. For thread designations see IS0 965-1 2 Normative references The follo
