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.
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.
International Standard ISO 965-1 was prepared by Technical Committee ISO/TC 1, Screw threads, Subcommittee
SC 2, Tolerances.
This third edition cancels and replaces the second edition (ISO 965-3:1980), which has been technically revised.
ISO 965 consists of the following parts, under the general title ISO general purpose metric screw threads –
Tolerances
– Part 1: Principles and basic data
– Part 2: Limits of sizes for general purpose bolt and nut threads – Medium quality
– Part 3: Deviations for constructional screw threads
– Part 4: Limits of sizes for hot-dip galvanized external threads to mate with internal threads tapped with tolerance
position H or G after galvanizing
– Part 5: Limits of sizes for internal screw threads to mate with hot-dip galvanized external screw threads with
maximum size of tolerance position h before galvanizing

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0
member bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
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.
International Standard IS0 965-l was prepared by Technical Committee ISOmC 1, Screw threads, Subcommittee
SC 2, Tolerances.
This third edition cancels and replaces the second edition (IS0 9653:1980), which has been technically revised.
IS0 965 consists of the following parts, under the general title /SO genera/ purpose metric screw threads -
Tolerances
- Part I: Principles and basic data
- Part 2: Limits of sizes for general purpose bolt and nut threads - Medium quality
- Part 3: Deviations for constructional screw threads
- Part 4: Limits of sizes for hot-dip galvanized external threads to mate with internal threads tapped with tolerance
position H or G after galvanizing
- Part 5: Limits of sizes for internal screw threads to mate with hot-dip galvanized external screw threads with
maximum size of tolerance position h before galvanizing

IS0 general purpose metric screw threads - Tolerances -
Part 3:
Deviations for constructional screw threads
1 Scope
This part of IS0 965 specifies deviations for pitch and crest diameters for IS0 general purpose metric screw threads (M)
conforming to IS0 261 having basic profile according to IS0 68-1.
The deviations specified are derived from the fundamental deviations and tolerances specified in IS0 965-l.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 965.
At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements
based on this part of IS0 965 are encouraged to investigate the possibility of applying the most recent editions of the
standards indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards.
IS0 68-1 :I 998, /SO general purpose screw threads - Basic profile - Part I: Metric screw threads.
IS0 261 :I 998, IS0 general purpose metric screw threads - General plan.
- Par? I: Principles and basic data.
IS0 965-l : 1998, IS0 general purpose metric screw threads - Tolerances
IS0 5408: 1983, Cylindrical screw threads - Vocabulary.
3 Definitions
For the purpose of this part of IS0 965 the definitions given in IS0 5408 apply.
4 Deviations
For internal threads as well as external threads, the actual root contour shall not in any point transgress the basic profile.
H
The tabulated deviation values for the minor diameter of the external thread are calculated on the basis of - truncation and
6
H
may be used for stress calculations deviation = - (e.~i + - .

[ ( 11
For coated threads, the tolerances apply to the parts before coating, unless otherwise stated. After coating the actual thread
profile shall not in any point transgress the maximum material limits for position H or h respectively.
NOTE These provisions are intended for thin coatings, for example those obtained by electroplating.

ISO 965-3:1998(F)
Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales, en
liaison avec l'ISO, participent également aux travaux. L'ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour
vote. Leur publication comme Normes internationales requiert l'approbation de 75 % au moins des comités
membres votants.
La Norme internationale ISO 965-3 a été élaborée par le comité technique ISO/TC 1, Filetages, sous-comité SC 2,
Tolérances.
Cette troisième édition annule et remplace la deuxième édition (ISO 965-3:1980), dont elle constitue une révision
technique.
L’ISO 965 comprend les parties suivantes, présentées sous le titre général Filetages métriques ISO pour usages
généraux — Tolérances:
 Partie 1: Principes et données fondamentales
 Partie 2: Dimensions limites pour filetages intérieurs et extérieurs d'usages généraux — Qualité moyenne
 Partie 3: Écarts pour filetages de construction
 Partie 4: Dimensions limites pour filetages extérieurs galvanisés à chaud pour assemblages avec des filetages
intérieurs de position de tolérance H ou G après galvanisation
 Partie 5: Dimensions limites pour filetages intérieurs pour assemblages avec des filetages extérieurs
galvanisés à chaud de position de tolérance maximale h avant galvanisation

Filetages métriques ISO pour usages généraux — Tolérances —
Partie 3:
Écarts pour filetages de construction
1 Domaine d’application
La présente partie de l'ISO 965 spécifie les dimensions limites pour les diamètres sur flancs et les diamètres au
sommet pour les filetages ISO métriques (M) pour usages généraux, conformément à l'ISO 261, de profil de base
conforme à l'ISO 68-1.
Les écarts spécifiés sont dérivés des écarts fondamentaux et des tolérances spécifiés dans l'ISO 965-1.
2 Références normatives

Pour les filetages revêtus, les tolérances s'appliquent, sauf spécification contraire, aux filetages avant revêtement.
Après revêtement, le profil réel ne doit dépasser la limite du maximum de matière en aucun point pour les positions
H ou h, respectivement.
NOTE Ces dispositions sont valables pour des revêtements minces, par exemple pour ceux obtenus par dépôt
électrolytique.
