(Main)Fasteners - Hexagon thin nuts (style 0), with fine pitch thread (ISO 8675:2023)
Fasteners - Hexagon thin nuts (style 0), with fine pitch thread (ISO 8675:2023)
This document specifies the characteristics of hexagon thin nuts (style 0), in steel and stainless steel, with metric fine pitch thread 8 mm to 64 mm, and with product grades A and B.
Thin nuts used as jam nuts are to be assembled together with a regular or high nut.
WARNING — Thin nuts (style 0) have a reduced loadability compared to regular nuts or high nuts, and are not designed to provide resistance to thread stripping (see ISO 898-2).
If in certain cases other specifications are requested, stainless steel grades and property classes can be selected from ISO 3506-2.
Verbindungselemente - Niedrige Sechskantmuttern (Typ 0), mit metrischem Feingewinde (ISO 8675:2023)
Dieses Dokument legt die Eigenschaften von niedrigen Sechskantmuttern (Typ 0) aus Stahl und nicht-rostendem Stahl mit metrischen Feingewinden 8 mm bis 64 mm und mit Produktklassen A und B fest.
Niedrige Muttern, die als Kontermuttern verwendet werden, müssen gemeinsam mit einer normalen Mutter oder einer hohen Mutter montiert werden.
WARNUNG — Niedrige Muttern (Typ 0) haben im Vergleich zu normalen oder hohen Muttern eine reduzierte Belastbarkeit und sind nicht dafür ausgelegt, dem Abstreifen des Gewindes standzuhalten (siehe ISO 898 2).
Falls in bestimmten Fällen andere Festlegungen benötigt werden, können nichtrostende Stahlsorten und Festigkeitsklassen aus ISO 3506 2 gewählt werden.
Fixations - Écrous bas hexagonaux (style 0), à pas fin (ISO 8675:2023)
Le présent document spécifie les caractéristiques des écrous bas hexagonaux (style 0), en acier et en acier inoxydable, à filetage métrique à pas fin de diamètres 8 mm à 64 mm, et de grades A et B.
Les écrous bas utilisés comme contre-écrou sont à assembler avec un écrou normal ou un écrou haut.
AVERTISSEMENT — Les écrous bas (style 0) ont une capacité de charge réduite par rapport aux écrous normaux ou hauts, et ne sont pas conçus pour fournir une résistance à l’arrachement des filets (voir ISO 898-2).
Si dans certains cas d’autres spécifications sont requises, les grades d’acier inoxydable et les classes de qualité peuvent être choisis dans l'ISO 3506-2.
Vezni elementi - Šestrobe nizke matice (tip 0), z drobnim navojem (ISO 8675:2023)
Ta dokument določa značilnosti šestrobih nizkih matic (tip 0) iz jekla in nerjavnega jekla, z drobnim navojem velikosti od 8 mm do 64 mm ter razredoma izdelave A in B.
Nizke matice, ki se uporabljajo kot tesnilne matice, je treba sestaviti skupaj z običajno ali visoko matico.
OPOZORILO: Nizke matice (tip 0) imajo manjšo obremenljivost v primerjavi z običajnimi maticami ali visokimi maticami in niso zasnovane tako, da zagotavljajo odpornost proti pobiranju navojev (glej ISO 898-2).
Če se v določenih primerih zahtevajo druge specifikacije, je tipe nerjavnega jekla in razrede lastnosti mogoče izbrati v skladu s standardom ISO 3506-2.

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, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/TC 185, Fasteners, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 8675:2012) which has been technically
revised.
The main changes are as follows:
— the use of thin nuts and a warning in relation to lower thread stripping resistance have been added
in scope;
— nuts with D > 39 mm (not included in ISO 898-2 and ISO 3506-2) have been dealt with in normative
Annex A;
— M18×2 and M22×2 have been added;
— for steel nuts, quenching and tempering condition has been specified in accordance with ISO 898-2;
— for stainless steel nuts, grades D4 and D6 and property class 040 have been added;
— non-ferrous metal nuts have been deleted (as a consequence of the withdrawal of ISO 8839);
— specifications for marking and labelling have been added as Clause 6.
