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. Esch 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 patt 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 3506-3 was prepared by Technical Committee
ISO/TC 2, fasteners, Sub-Committee SC 1, Mechanical properlies of
fasteners.
This first edition, together with ISO 3506-1 and ISO 3506-2, cancels and
replaces ISO 3506:1979, which has been technically revised.
ISO 3506 consists of the following Patts, under the general title Mechanical
properfies of corrosion-resistant stainless-steel fasteners.
- Parf 1: Belts, screws and studs
- Part2: Nuts
- Parf 3: Set screws and similar fasteners not under tensile stress

Introduction
In the preparation of this part of ISO 3506 special attention has been given
to the fundamentally different property characteristics of the stainless steel
fastener grades compared with those of carbon steel and low-alloy steel
fasteners. Austenitic stainless steels are strengthened only by cold working
and consequently the components do not have as homogeneous a condition
as hardened and tempered Parts. These special features have been
recognized in the elaboration of the property classes and the test procedures
for mechanical properties.

Mechanical properties of corrosion-resistant stainless-steel fasteners -
Part 3:
Set screws and similar fasteners nst under tensile stress
1 Scope
This patt of ISO 3506 specifies the mechanical proper-Ges of set screws and similar fasteners not under tensile stress
made of austenitic stainless steel when tested over an ambient temperature range of 15 “C to 25 OC. Propet-ties will
vary at higher or lower temperatures.
It applies to set screws and similar fasteners
- with nominal thread diameters (d) fram i,6 mm up to and including 24 mm;
- of triangular ISO metric threads with diameters and pitches according to ISO 68-1, ISO 261 and ISO 262;
- of any shape.
lt does not apply to screws with special properties such as weldability.
This patt of ISO 3506 does not define corrosion or Oxidation resistance in particular environments.
The aim of this part sf ISO 3506 is a classification into property classes of corrosion resistant stainless steel
fasteners. Corrosion and Oxidation performances and mechanical properties for use at elevated or sub-zero
temperatures must be the subject of agreement between user and manufacturer in each particular case. Annex D
Shows how the risk of intergranular corrosion at elevated temperatures depends on the carbon content.
All austenitic stainless steel fasteners are normally non-magnetic in the annealed condtition; after cold working,
some magnetic proper-Ges may be evident (see annex E).

3 Designation, marking and finish
3.1 Designation
The designation System for stainless steel grades and property classes for set screws and similar fasteners is shown
in figure 1. The designation of the material consists of two blocks which are separated by a hyphen. The first block
designates the steel grade, the second block the property class.
The designation of the steel grade (first block) consists of the Ietter
A for austenitic steel
which indicates the group of steel and a digit which indicates a range of Chemical compositions within this steel
group.
The designation of the property class (second block) consists of two digits representing l/lO of the minimum Vickers
hardness and the Ietter H referring to hardness, see table 1.
