Toleranzen für Verbindungselemente - Teil 1: Schrauben und Muttern - Produktklassen A, B und C (ISO 4759-1:2000)
Diese Internationale Norm legt eine Auswahl von Toleranzen für Schrauben und Muttern mit ISO-Metrischem Gewinde und Produktklassen A, B, und C und für Blechschrauben mit Produktklasse A fest. ANMERKUNG 1: Die Bilder sind Beispiele um die Anwendung der Maße, die mit Toleranzen versehen sind, zu verdeutlichen. Hinsichtlich der bildichen Darstellung wird auf ISO 8015 verwiesen. Die Toleranzen, mit Ausnahme der Toleranzen für Gewinde, wurden aus dem System "Toleranzen und Passungen" nach ISO 286-1 und ISO 286-2 ausgewählt.
Tolérances des éléments de fixation - Partie 1: Vis, goujons et écrous - Grades A, B et C (ISO 4759-1:2000)
La présente partie de l'ISO 4759 spécifie une sélection de tolérances pour les vis, goujons et écrous à filetage métrique ISO et de grades A, B et C ainsi que pour les vis à tôle de grade A.
NOTE 1: Les grades se référent à l'étendue des tolérances, le grade A étant le plus précis et le grade C le moins précis. Les tolérances, à l'exception des tolérances de filetage, sont sélectionnées d'après le système de tolérances et d'ajustements spécifié dans l'ISO 286-1 et l'ISO 286-2. Les tolérances pour le filetage métrique sont issues de la serie de classes de tolérances spécifiées dans l'ISO 965-3; les tolérances pour les filetages de vis à tôle sont traitées dans l'ISO 1478. Les tolérances de forme et de position sont spécifiées et indiquées conformément à l'ISO 1101, à l'ISO 8015 et à l'ISO 2692. Les tolérances spécifiées dans la présente partie de l'ISO 4759 s'appliquent, sauf spécification contraire, aux éléments de fixation avant revêtement. Voir également l'ISO 4042. Des écarts par rapport aux tolérances spécifiées dans la présente partie de l'ISO 4759 ne sont autorisés dans les normes de produits que pour des raisons techniques valables. Lorsqu'il existe une différence entre les prescriptions de tolérance de la présente partie de l'ISO 4759 et de la norme de produit, la norme de produit est prioritaire. Il est recommandé d'utiliser également ces tolérances pour les éléments de fixation non normalisés. Les dimensions et tolérances données dans la présente partie de l'ISO 4759 sont en millimètres.

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 part of ISO 4759 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 4759-1 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee
SC 7, Reference Standards for fasteners (mainly covering terminology, dimensioning, sizes and tolerancing).
This second edition cancels and replaces the first edition (ISO 4759-1:1978), which has been technically revised.
ISO 4759 consists of the following parts, under the general title Tolerances for fasteners:
� Part 1: Bolts, screws, studs and nuts — Product grades A, B and C
� Part 3: Plain washers for bolts, screws ans nuts — Product grades A and C
Annexes A to C of this part of ISO 4759 are for information only.

INTERNATIONAL STANDARD ISO 4759-1:2000(E)
Tolerances for fasteners —
Part 1:
Bolts, screws, studs and nuts — Product grades A, B and C
1 Scope
This part of ISO 4759 specifies a selection of tolerances for bolts, screws, studs and nuts with ISO metric threads
and with product grades A, B and C and for tapping screws with product grade A.
NOTE The product grades refer to the size of the tolerances where grade A is the most precise and grade C is the least
precise.
The tolerances, except tolerances for threads, are selected from the system of limits and fits specified in ISO 286-1
and ISO 286-2. The tolerances for metric threads are taken from the series of tolerance classes specified in
ISO 965-3. The tolerances for tapping screw threads are covered in ISO 1478.
The tolerances of form and position are specified and indicated in accordance with ISO 1101, ISO 8015 and
ISO 2692.
The tolerances specified in this part of ISO 4759 apply to fasteners prior to coating unless otherwise specified. See
also ISO 4042.
Deviations from the tolerances specified in this part of ISO 4759 are only permitted in product standards where
there are valid technical reasons. In cases where there is a difference between the tolerance requirements in this
part of ISO 4759 and the product standard, the product standard takes precedence.
It is recommended that these tolerances also be used for non-standard fasteners.
Dimensions and tolerances given in this part of ISO 4759 are in millimetres.
