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 12, Fasteners
with metric internal thread.
This fourth edition cancels and replaces the third edition (ISO 7042:2012) which has been technically
revised.
The main changes are as follows:
— the design principles of these nuts have been clarified in scope (see Note);
— style, relevant property classes and related quenching and tempering conditions for steel nuts have been
specified in Clause 5 in accordance with ISO 898-2 (see Table 3);
— stainless steel nuts have been added in accordance with ISO 3506-2;
— M7, M18, M22, M27, M33 and M39 have been added;
— d has been specified with two decimal places;
a,max
— d for M5 has been changed from s – IT16 to s – IT15 in order to have a larger bearing surface

area and thus less contact pressure;
— h for M12 has been corrected to 12,30 mm (13,30 mm in the third edition came from a typing error);
max
h for M24 has been increased to 24,00 mm in order to have h ≥ D for the whole diameter range;
max max
— specifications for marking and labelling have been added as Clause 6.

1 Scope
This document specifies the characteristics of prevailing torque (all metal) hexagon high nuts, in steel and
stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.
NOTE These nuts are designed with an overall heigth h = m (as specified in ISO 898-2 and ISO 4033 for style
