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

This document was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 11,
Fasteners with metric external thread.
This second edition cancels and replaces the first edition (ISO 7434:1983), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— angle of the point, β , 90° ± 2° and 120° ± 2° changed to reference value without tolerance, i.e. β
ref
shall be 90° or 120°;
— for M2, M3 and M3,5, l = 3, l = 4 and l = 5 have been classified to short standard length separately in
order to get 4,5 to 6 full thread turns;
— for stainless steel screws, grades A2 and A4 with hardness classes 12H and 21H have been added;
— non-ferrous metal screws have been deleted;
— mechanical properties of steel and stainless steel screws have been added for d < 1,6 mm (“As
agreed”) in Table 2;
— “plain” has been changed to “as processed” for steel screws and to “Clean and bright” for stainless
steel screws in Table 2;
— non-electrolytically applied zinc flake coating has been added for steel screws, and “Passivated” has
been added for stainless steel screws in Table 2;
— the requirement of surface discontinuities has been added for steel screws;
— specifications for marking and labelling have been added as Clause 6.
