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 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 the following

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 4015:1979), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— M3,5, M7 and M18 have been added;

— the indentation on the head and the washer face under the head have been left to the choice of the

manufacturer, however limits for dimensions have been added;

— d has been changed for sizes d  M5 from s - IT16 to s - IT15 in order to have a larger

w,min min min

bearing surface area (and less contact pressure), and its values for d > M5 have been recalculated in

accordance with ISO 4759-1 without rounding off;

— values for k have been recalculated in accordance with ISO 4759-1 without rounding off,

w,min
— value for e has been corrected for M3;
min

— property class 50 was has been added for stainless steel, and non-ferrous metal has 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

Hexagon head bolts with reduced shank (shank diameter  pitch
diameter) — Product grade B
1 Scope

This document specifies the characteristics of hexagon head bolts with reduced shank (shank diameter

 pitch diameter), in steel and stainless steel, with metric coarse pitch threads M3 to M20, and with

product grade B.

NOTE 1 If in certain cases other specifications are requested, property classes and stainless steel grades can be

selected from ISO 898-1 or ISO 3506-1, and dimensional options from ISO 888 or ISO 4753.

NOTE 2 For hexagon head bolts with full shank, see ISO 4014.
