La présente Norme internationale prescrit les caractéristiques des clous cannelés à tête fraisée, à trois cannelures constantes sur toute leur longueur, débouchantes d'un côté et régulièrement espacées, de diamètre nominal, d1, de 1,4 mm à 20 mm inclus. Le matériau refoulé de chaque côté des cannelures forme un renflement dont le diamètre d2, supérieur au diamètre nominal d1, permet un ajustement serré de ces clous cannelés lorsqu'ils sont emmanchés en force dans un trou de diamètre de perçage égal au diamètre nominal du clou d1 (voir article 4).

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 and by Technical Committee
CEN/TC 185, Fasteners in collaboration.
This third edition cancels and replaces the second edition (ISO 8747:1997) which has been technically
revised.
The main changes are as follows:
— terms and definitions, principles for grooved pins and assembly (including hole dimensions), control
of the expanded diameter d and pin straightness, mechanical and physical properties (including
shear resistance and hardness) and inspection which are common for all grooved pins (product
standards ISO 8739 to ISO 8747, ISO 13670 and ISO 13672) have been specified in the new reference
standard ISO 13669, general requirements;
— nominal sizes 1,4 mm and 1,6 mm have been deleted;
— the symbols for the pilot point (PL instead of B) and optional chamfer point (CH instead of A) have
been amended analogously to ISO 4753; the length of the points has been specified as a minimum
value;
— the head diameters d have been recalculated and rounded to the nearest 0,05 mm for pins with
k
nominal sizes up to 8 mm; d has been recalculated for pins with nominal sizes 16 mm and
k,max
20 mm;
— the head height k has been added as a reference dimension;
— the maximum distance between the underhead bearing surface and the beginning of the grooves l
k
has been added;
— stainless steel grades A2, A4, C1 and F1 have been added;
— other materials (such as hardened steels, brass, aluminium) are by agreement (see Table 3);

ISO/DIS 8747:2023(E)
— specifications for labelling have been added as Clause 8.
