Foreword
ISO (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 which 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 matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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 responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 11,
Fasteners with metric external thread, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/TC 185, Fasteners, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 8676:2011), which has been technically
revised.
The main changes are as follows:
— tables for dimensions have been entirely restructured, so that the user can find the specified values
in a reliable manner (no risk of picking the wrong dimension), see Clause 4 and Annex A;
— the rules for the shortest and greatest standard lengths have been added, and they have been
amended accordingly (shortest lengths erroneously published with l = 40 mm in the version
nom
of 2011 have been restored for M22×2, M30×2 and M36×3); standard greatest lengths have been
limited to 200 mm (longer lengths are to be agreed between the purchaser and the manufacturer);
— for steel screws, property class 5.6 has been deleted and property class 12.9/12.9 has been added;
— for stainless steel screws, grades D4 and D6 and property class 80 have been added;
— non-ferrous metal screws have been deleted;
— specifications for marking and labelling have been added as Clause 6.
Any feedback or questions on this document should be directed to the user’s national standards body. A
