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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO's adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 2, Fasteners, Subcommittee SC 12, Fasteners
with metric internal thread.
This fifth edition cancels and replaces the fourth edition (ISO 8673:2012).
The main changes compared to the previous edition are as follows:
— nuts with D > 39 mm (with m < 0,8D not conforming to ISO 898-2) have been shifted to informative
min
Annex A; reference to ISO/TR 16224 for appropriate nut design has been added;
— M18×2 and M22×2 have been added;
— d , d and m have been specified with two decimal places;
a,max w,min w,min
— for steel nuts, quenching and tempering condition has been specified in accordance with ISO 898-2,
and property class 12 has been added;
— for stainless steel nuts, grades D4 and D6 and property class 80 have been added;
— non-ferrous metal nuts have been cancelled (as a consequence of the cancellation of ISO 8839);
— 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
