Fasteners - Mechanical properties of corrosion resistant stainless steel fasteners - Part 3: Set screws (and similar fasteners not under tensile stress) with specified grades and hardness classes (ISO/FDIS 3506-3:2024)
ISO 3506-3:2009 specifies the mechanical properties of set screws and similar fasteners not under tensile stress made of austenitic stainless steel, when tested over an ambient temperature range of 10 °C to 35 °C. Properties vary at higher or lower temperatures.
ISO 3506-3:2009 applies to set screws and similar fasteners:
- with nominal thread diameter 1,6 mm ≤ d ≤ 24 mm;
- of triangular ISO metric threads with diameters and pitches in accordance with ISO 68-1, ISO 261 and ISO 262;
- of any shape.
It does not apply to screws with special properties, such as weldability.
Mechanische Verbindungselemente - Eigenschaften von Verbindungselementen aus nichtrostenden Stählen - Teil 3: Gewindestifte und ähnliche nicht auf Zug beanspruchte Verbindungselemente (ISO/FDIS 3506-3:2024)
Dieses Dokument legt die mechanischen und physikalischen Eigenschaften von nicht auf Zug beanspruchten Gewindestiften und ähnlichen Verbindungselementen aus nichtrostenden, korrosionsbeständigen austenitischen Stählen und Duplex-Stählen mit festgelegten Stahlsorten und Härteklassen fest.
WARNUNG — Gewindestifte, die den Anforderungen dieses Dokuments entsprechen, werden in einem Umgebungstemperaturbereich von 10 °C bis 35 °C geprüft und in einem Anwendungsbereich von −20 °C bis +150 °C eingesetzt. Eventuell ändern sich die festgelegten mechanischen und physikalischen Eigenschaften bei höheren und/oder niedrigeren Temperaturen. Es liegt daher in der Verantwortung des Anwenders, auf der Grundlage der Betriebsumgebungsbedingungen der Baugruppe die geeignete Auswahl zu treffen (siehe auch Abschnitt 5 und Abschnitt 6).
Dieses Dokument gilt für Gewindestifte und ähnliche Verbindungselemente, die nicht auf Zug beansprucht werden
mit metrischem ISO-Gewinde nach ISO 68 1,
mit Durchmesser-Steigungs-Kombinationen nach ISO 261 und ISO 262,
mit Gewindenenndurchmessern 1,6 mm bis 24 mm,
mit Gewindetoleranzen nach ISO 965 1 und ISO 965 2,
mit festgelegten Härteklassen, und
mit beliebiger Form.
ANMERKUNG Der Begriff Gewindestift wird im Folgenden für alle nicht auf Zug beanspruchten Schrauben und ähnlichen Verbindungselemente verwendet, die in den Anwendungsbereich dieses Dokuments fallen.
Dieses Dokument gilt nicht für Schrauben, die auf Zug beansprucht werden (siehe ISO 3506 1). Es legt keine Anforderungen für funktionelle Eigenschaften wie Scherfestigkeit oder Schweißbarkeit fest.

Introduction
The properties of stainless steel fasteners result from the chemical composition of the material
(especially corrosion resistance) and from the mechanical properties due to the manufacturing
processes. Austenitic and duplex (austenitic-ferritic) stainless steel fasteners are generally
manufactured by cold working; they consequently do not have homogeneous local material properties
when compared to quenched and tempered fasteners.
Austenitic-ferritic stainless steels referred to as duplex stainless steel grades were originally invented
in the 1930s and have been increasingly used since the 1980s. This document was revised to reflect
their standardization for fasteners.
All duplex stainless steel grades show improved resistance to stress corrosion cracking compared to
the commonly used A2 to A5 austenitic grades. Most duplex grades also show higher levels of pitting
corrosion resistance, where D2 matches at least A2 and where D4 matches at least A4.
Complementary detailed explanations about stainless steel grades and properties are specified in
ISO 3506-6.

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).
