INTERNATIONAL Iso STANDARD 4014 “Third edition 1909-09-01 Hexagon head bolts — Product grades A and B Vis a téte hexagonale partiellement filetées — Grades A et B Reference number 1S0 4014:1999(E)ISO 4014:1999(E) Foreword ISO (the Intemational 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 which a technical committee has been established has the right to be represented on that committee. Intemational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Flectrotechnical Commission (IEC) on all matters of electrotachnical standardization International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft international Standards adopted by the technical committees are circulated to the member bodies for voting Publication as an Intemational Standard requires approval by at least 75 % of the member bodies casting a vole. International Standard ISO 4014 was prepared by Technical Committee ISO/TC 2, Fasteners, This third edition cancels and replaces the second edition (ISO 4014:1988) which has been technically revised. © 180 1000 All rights reserved.

The series comprises: a) hexagon head bolts (ISO 4014 to ISO 4016 and ISO 8765); b) hexagon head screws (ISO 4017, ISO 4018 and ISO 8676); c) hexagon nuts (ISO 4032 to ISO 4036, ISO 8673 to ISO 8675); d) hexagon bolts with flange (/SO 4162 and ISO 15071); e) hexagon nuts with flange (|SO 4161 and ISO 10663); ) structural bolts and nuts (ISO 4775, ISO 7411 to ISO 7414 and ISO 7417).INTERNATIONAL STANDARD @1SO ISO 4014:1999(E) Hexagon head bolts — Product grades A and B 1 Scope This International Standard specifies the characteristics of hexagon head bolts with threads from M1,6 up to and including M64, of product grade A for threads M1,6 to M24 and nominal lengths up to and including 10 ¢ or 150 mm, whichever is shorter and product grade B for threads over M24 or nominal lengths over 10 d or 150 mm, whichever is shorter. If, in special cases, specifications other then those listed in this International Standard are required, they should be selected from existing International Standards, for example ISO 724, ISO 888, ISO 898-1, ISO 965-1, ISO 3506-1, ISO 4753 and ISO 4759-1 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this Intemational Standard. For dated references. subsequent amendments to, or revisions of, any of these publications do not epply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
