(Main)Mechanical properties of fasteners made of carbon steel and alloy steel - Part 1: Bolts, screws and studs with specified property classes - Coarse thread and fine pitch thread (ISO 898-1:2013)
Mechanical properties of fasteners made of carbon steel and alloy steel - Part 1: Bolts, screws and studs with specified property classes - Coarse thread and fine pitch thread (ISO 898-1:2013)
ISO 898-1:2009 specifies mechanical and physical properties of bolts, screws and studs made of carbon steel and alloy steel when tested at an ambient temperature range of 10 °C to 35 °C. Fasteners — the term used when bolts, screws and studs are considered all together — that conform to its requirements are evaluated at that ambient temperature range. Information is given on fasteners that do not retain the specified mechanical and physical properties at elevated temperatures and/or lower temperatures.
ISO 898-1:2009 excludes certain fasteners that do not fulfil its tensile or torsional requirements because the geometry of their heads reduce the shear area in the head compared to the stress area in the thread. These include fasteners having a low head, with or without external driving feature, a low round or cylindrical head with internal driving feature or a countersunk head with internal driving feature (see 8.2).
It is applicable to bolts, screws and studs made of carbon steel or alloy steel, having a triangular ISO metric screw thread according to ISO 68-1, with a coarse pitch thread M1,6 to M39, and fine pitch thread M8´1 to M39´3, with diameter/pitch combinations according to ISO 261 and ISO 262, having thread tolerances according to ISO 965-1, ISO 965-2 and ISO 965-4.
It is not applicable to set screws and similar threaded fasteners not under tensile stresses (see ISO 898-5).
It does not specify requirements for such properties as weldability, corrosion resistance, resistance to shear stress, torque/clamp force performance, or fatigue resistance.
Mechanische Eigenschaften von Verbindungselementen aus Kohlenstoffstahl und legiertem Stahl - Teil 1: Schrauben mit festgelegten Festigkeitsklassen - Regelgewinde und Feingewinde (ISO 898-1:2013)
Dieser Teil von ISO 898 legt mechanische und physikalische Eigenschaften von Schrauben aus Kohlenstoff-stahl und legiertem Stahl fest, die in einem Bereich der Umgebungstemperatur von 10 °C bis 35 °C geprüft werden. Schrauben (im Englischen als „fasteners“ bezeichnet, wenn gleichzeitig „bolts“, „screws“ und „studs“ angesprochen werden), die den Anforderungen dieses Teils von ISO 898 entsprechen, werden in diesem Bereich der Umgebungstemperatur bewertet. Es kann sein, dass sie die festgelegten mechanischen und physikalischen Eigenschaften bei höheren Temperaturen (siehe Angaben in Anhang B) und/oder niedrigeren Temperaturen nicht beibehalten.
ANMERKUNG 1 Schrauben, die den Anforderungen dieses Teils von ISO 898 entsprechen, werden für Anwendungen im Bereich zwischen 50 °C und 150 °C eingesetzt. Anwender sollten für Temperaturen außerhalb des Bereiches von 50 °C bis 150 °C sowie bis zu einer Höchsttemperatur von 300 °C einen erfahrenen Metallurgen für Verbindungs¬elemente konsultieren, um die geeignete Wahl für die vorgesehene Anwendung zu treffen.
ANMERKUNG 2 Informationen zur Auswahl und Anwendung von Stählen für den Gebrauch bei niedrigeren und höheren Temperaturen sind z. B. in EN 10269, ASTM F2281 und in ASTM A320/A320M enthalten.
Bestimmte Schrauben erfüllen möglicherweise nicht die in diesem Teil von ISO 898 festgelegten Anforde-rungen an die Belastbarkeit unter Zug oder Torsion, weil wegen der Kopfgeometrie die Scherfläche im Kopf gegenüber dem Spannungsquerschnitt im Gewinde verkleinert ist. Dies betrifft Schrauben mit niedrigen Köpfen oder mit Senkköpfen (siehe 8.2).
Dieser Teil von ISO 898 gilt für Schrauben
- aus Kohlenstoffstahl und legiertem Stahl,
- mit Metrischem ISO-Gewinde nach ISO 68-1,
- mit Regelgewinde M1,6 bis M39 und Feingewinde M81 bis M393,
- mit Durchmesser-Steigungs-Kombinationen nach ISO 261 und ISO 262 und
- mit Gewindetoleranzen nach ISO 965-1, ISO 965-2 und ISO 965-4.
Er gilt nicht für Gewindestifte und ähnliche nicht auf Zug beanspruchte Verbindungselemente mit Gewinde (siehe ISO 898-5).
Er legt keine Anforderungen für Eigenschaften fest wie
- Schweißbarkeit,
- Korrosionsbeständigkeit,
- Scherfestigkeit,
- Drehmoment/Vorspannkraft-Verhalten (für Prüfverfahren, siehe ISO 16047) oder
- Dauerfestigkeit.
Caractéristiques mécaniques des éléments de fixation en acier au carbone et en acier allié - Partie 1: Vis, goujons et tiges filetées de classes de qualité spécifiées - Filetages à pas gros et filetages à pas fin (ISO 898-1:2013)
L'ISO 898-1:2009 spécifie les caractéristiques mécaniques et physiques des vis, goujons et tiges filetées en acier au carbone et en acier allié, essayés dans la plage de température ambiante de 10 °C à 35 °C. Les éléments de fixation — terme utilisé lorsque les vis, goujons et tiges filetées sont considérés dans leur ensemble — conformes aux exigences de la présente partie de l'ISO 898 sont évalués uniquement dans cette plage de températures ambiantes. Des informations sont données pour les éléments de fixation qui ne conservent pas les caractéristiques mécaniques et physiques spécifiées à des températures élevées et/ou inférieures.
Certains éléments de fixation peuvent ne pas satisfaire aux exigences de l'ISO 898-1:2009 concernant la résistance à la traction ou à la torsion, en raison de la géométrie de la tête (section cisaillée dans la tête inférieure à la section résistante dans le filetage). Ceux-ci comprennent les éléments de fixation à tête réduite, avec ou sans entraînement externe, à tête bombée plate et cylindrique basse avec entraînement interne ou à tête fraisée avec entraînement interne.
La présente partie de l'ISO 898 s'applique aux vis, goujons et tiges filetées en acier au carbone ou en acier allié, à filetage métrique ISO triangulaire conforme à l'ISO 68‑1, de filetage M1,6 à M39 (pour les pas gros) et de filetage M8 x 1 à M39 x 3 (pour les pas fins), de combinaisons diamètre/pas conformes à l'ISO 261 et à l'ISO 262, de tolérance de filetage conforme à l'ISO 965‑1, ISO 965‑2 et ISO 965‑4.
Elle ne s'applique pas aux vis sans tête et éléments de fixation filetés similaires non soumis à des contraintes de traction (voir l'ISO 898‑5).
Elle ne spécifie aucune exigence pour des caractéristiques telles que la soudabilité, la résistance à la corrosion, la résistance au cisaillement, la performance couple/tension, ou la résistance à la fatigue.
Mehanske lastnosti veznih elementov iz ogljikovega in legiranega jekla - 1. del: Vijaki s specificiranim trdnostnim razredom - Grobi in fini navoj (ISO 898-1:2013)
Ta del standarda ISO 898 določa mehanske in fizikalne lastnosti vijakov iz ogljikovega in legiranega jekla, kadar se preskušajo pri temperaturi okolja, in sicer od 10 °C do 35 °C. Vezni elementi (izraz, ki se uporablja za vse vijake skupaj), ki izpolnjujejo zahteve iz tega dela standarda ISO 898, se ovrednotijo pri tem temperaturnem razponu okolja. Vijaki pri višjih temperaturah (glej dodatek B) in/ali nižjih temperaturah morda ne ohranijo opredeljenih mehanskih in fizikalnih lastnosti. OPOMBA 1 Vezni elementi, ki izpolnjujejo zahteve iz tega dela standarda ISO 898, se uporabljajo pri temperaturah od –50 °C do +150 °C. Uporabnikom se priporoča, da se glede ustrezne izbire za določeno uporabo pri temperaturah zunaj območja –50 °C do +150 °C in do najvišje temperature +300 °C posvetujejo z izkušenim metalurgom za vezne elemente. OPOMBA 2 Informacije za izbiro in uporabo jekel za uporabo pri nižjih in višjih temperaturah so na primer na voljo v standardih EN 10269, ASTM F2281 in ASTM A320/A320M. Nekateri vijaki morda ne izpolnjujejo nateznih ali torzijskih zahtev iz tega dela standarda ISO 898, ker geometrija njihovih glav zmanjša strižno površino v glavi v primerjavi s površino obremenitve v navoju. Mednje spadajo tudi vijaki z nizko ali ugrezno glavo (glej točko 8.2). Ta del standarda ISO 898 se uporablja za vijake:
– iz ogljikovega ali legiranega jekla,
– s trikotnim ISO metrskim vijačnim navojem v skladu s standardom ISO 68-1,
– z grobim navojem M1,6 do M39 in drobnim navojem M8×1 do M39×3,
– s kombinacijami premer/navoj v skladu s standardoma ISO 261 in ISO 262 ter
– s tolerancami navojev v skladu s standardi ISO 965-1, ISO 965-2 in ISO 965-4. Ne uporablja se za navojne zatiče in podobne vijake z navojem, ki niso pod natezno obremenitvijo (glej standard ISO 898-5). Standard ne določa zahtev za lastnosti, kot so:
– varivost,
– odpornost proti koroziji,
– odpornost proti strižni napetosti,
– delovanje sile navora/ukleščenja (za preskusno metodo glej standard ISO 16047) ali
– odpornost proti utrujanju.

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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 898-1 was prepared by Technical Committee ISO/TC 2, Fasteners, Subcommittee SC 11, Fasteners with
metric external thread.
This fifth edition cancels and replaces the fourth edition (ISO 898-1:2009), of which it constitutes a minor
revision.
ISO 898 consists of the following parts, under the general title Mechanical properties of fasteners made of
carbon steel and alloy steel:
⎯ Part 1: Bolts, screws and studs with specified property classes — Coarse thread and fine pitch thread
⎯ Part 2: Nuts with specified property classes — Coarse thread and fine pitch thread
