ISO 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.
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 International
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
International Standard may be the subject of patent rights. ISO shall not be held
responsible for identifying any or all such patent rights.
International Standard ISO 7089 was prepared by Technical Committee ISO/TC
2, Fasteners.
This second edition cancels and replaces the first edition (ISO 7089.1983),
which has been technically revised.

including 8;
- hexagon bolts, screws and nuts of stainless steel and of similar chemical
composition;

- hexagon bolts and screws of product grades A and B in property classes
up to and including 10.9;
- hexagon nuts of product grades A and B in property classes up to and
including 10.
If dimensions other than those listed in this Standard are required, they should
be selected from those given in GB/T 5286.
