ISO 4014:2011(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 ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with theInternational Electrotechnical Commission (IEC) on all matters 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 Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational 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 patentrights. ISO shall not be held responsible for identifying any or all such patent rights.-- ,, ,,,, - - ,, ,, , ,, ---ISO 4014 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 10, Productstandards for fasteners.This fourth edition cancels and replaces the third edition (ISO 4014:1999), of which it constitutes a minorrevision.

ISO 4014:2011(E)IntroductionThis International Standard belongs to a complete group of product standards developed by ISO on externalhexagon drive fasteners. It comprises the following:a)hexagon head bolts (ISO 4014, ISO 4015, ISO 4016 and ISO 8765);b)hexagon head screws (ISO 4017, ISO 4018 and ISO 8676);c)hexagon nuts (ISO 4032, ISO 4033, ISO 4034, ISO 4035, ISO 4036, ISO 7040, ISO 7041, ISO 7042,ISO 7719, ISO 7720, ISO 8673, ISO 8674, ISO 8675, ISO 10511, ISO 10512 and ISO 10513);d)hexagon bolts with flange (ISO 4162, ISO 15071 and ISO 15072);e)hexagon nuts with flange (ISO 4161, ISO 7043, ISO 7044, ISO 10663, ISO 12125, ISO 12126 andISO 21670).-- ,, ,,,, - - ,, ,, , ,, ---ivCopyright InternationalOrganization for StandardizationProvided by IHS under license with ISONo reproduction or networking permitted without license from IHS ISO 2011 – All rights reservedNot for Resale

INTERNATIONAL STANDARDISO 4014:2011(E)Hexagon head bolts — Product grades A and B1ScopeThis International Standard specifies the characteristics of hexagon head bolts with threads from M1,6 up toand including M64, of product grade A for threads M1,6 to M24 and nominal lengths up to and including 10d or150 mm, whichever is the shorter, and product grade B for threads over M24 or nominal lengths over 10d or150 mm, whichever is the shorter.If, in special cases, specifications other than those listed in this International Standard are required, they canbe selected from existing International Standards, for example ISO 724, ISO 888, ISO 898-1, ISO 965-1,ISO 3506-1, ISO 4753 and ISO 4759-1.2Normative referencesThe following referenced documents are indispensable for the application of this document.
