This document specifies the mechanical and physical properties of bolts, screws and studs, with coarse pitch thread and fine pitch thread, made of corrosion-resistant stainless steels, when tested at the ambient temperature range of 10 °C to 35 °C. It specifies property classes in relation to austenitic, martensitic, ferritic and duplex (austenitic-ferritic) steel grades for fasteners.
The term "fasteners" is used in this document when bolts, screws and studs are considered all together.
ISO 3506‑6 provides general rules and additional technical information on suitable stainless steels and their properties.
Fasteners conforming to the requirements of this document are evaluated at the ambient temperature specified in paragraph 1. It is possible that they do not retain the specified mechanical and physical properties at elevated and/or lower temperatures.
NOTE 1 Fasteners conforming to the requirements of this document are used without restriction in applications ranging from ?20 °C to +150 °C; however, fasteners conforming to this document are also used for applications outside this range down to ?196 °C and up to +300 °C. For more details, see Annex A and ISO 3506‑6.
Outside the temperature range of ?20 °C to +150 °C, it is the responsibility of the user to determine the appropriate choice for a given application in consultation with an experienced fastener metallurgist and by taking into account e.g. stainless steel composition, duration of exposure at elevated or low temperature, the effect of the temperature on the fasteners mechanical properties and clamped parts, and the corrosive service environment of the bolted joint.
NOTE 2 ISO 3506‑5 is developed in order to assist in the selection of appropriate stainless steel grades and property classes intended for use at temperatures up to +800 °C.
This document applies to bolts, screws and studs:
— with ISO metric thread in accordance with ISO 68‑1,
— with diameter/pitch combinations in accordance with ISO 261 and ISO 262,
— with coarse pitch thread M1,6 to M39, and fine pitch thread M8×1 to M39×3,
— with thread tolerances in accordance with ISO 965‑1 and ISO 965‑2,
— with specified property classes, and
— of any shape.
Stainless steel grades and property classes can be used for sizes outside the diameter limits of this document (i.e. for d < 1,6 mm or d > 39 mm), provided that all applicable chemical, mechanical and physical requirements are met.
Certain bolts, screws and studs might not fulfil the tensile or torsional requirements of this document because of the geometry of their head or unthreaded shank, thus resulting in reduced loadability (e.g. when shear area in the head is less than the stress area in the thread; see 8.2.2).
This document does not apply to set screws and similar threaded fasteners not under tensile stress (see ISO 3506‑3).
It does not specify requirements for functional properties such as:
— torque/clamp force properties,
— shear strength,
— fatigue resistance, or
— weldability.

This document specifies the characteristics of hexagon socket countersunk head screws with reduced loadability due to head design, in steel and stainless steel, with metric coarse pitch threads M2 to M20, and with product grade A.
NOTE 1 Other dimensional options are given in ISO 888, ISO 965-1 and ISO 4753.
NOTE 2 The reduced loadability (related to the countersunk head dimensions in combination with penetration of the hexagon socket specified in this document) implies a limitation of ultimate tensile load; see Table 5.
NOTE 3 Particular attention is needed to ensure alignment of the countersunk head with the bearing surface of the countersink in the assembly.

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.

ISO 898-5:2012 specifies mechanical and physical properties of set screws and similar threaded fasteners made of carbon steel or alloy steel when tested at an ambient temperature range of 10 °C to 35 °C. Fasteners (the term used when set screws and similar threaded fasteners are considered all together) which conform to the requirements of ISO 898-5:2012 are evaluated at that ambient temperature range.
Fasteners according to ISO 898-5:2012 are classified to specified hardness classes and are intended for use under compressive stress only.
ISO 898-5:2012 is applicable to set screws and similar fasteners:
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 M30, and fine pitch thread M8×1 to M30×2,
with diameter/pitch combinations according to ISO 261 and ISO 262, and
having thread tolerances according to ISO 965-1 and ISO 965-2.

This part of ISO 898 specifies mechanical and physical properties of nuts with coarse thread and fine pitch
thread made of carbon steel and alloy steel when tested at an ambient temperature range of 10 °C to 35 °C.
Nuts conforming to the requirements of this part of ISO 898 are evaluated at that ambient temperature range.
It is possible that they do not retain the specified mechanical and physical properties at elevated and/or lower
temperatures.
NOTE 1 Nuts conforming to the requirements of this part of ISO 898 have been used in applications
ranging from ?50 °C to +150 °C. It is the responsibility of users to consult an experienced fastener materials expert
for temperatures outside the range of ?50 °C to +150 °C and up to a maximum temperature of +300°C to determine
appropriate choices for a given application.
NOTE 2 Information for the selection and application of steels for use at lower and elevated temperatures is given for
instance in EN 10269, ASTM F2281 and in ASTM A320/A320M.
This part of ISO 898 is applicable to nuts:
a) made of carbon steel or alloy steel;
b) with coarse thread M5 ≤ D ≤ M39, and fine pitch thread M8×1 ≤ D ≤ M39×3;
c) with triangular ISO metric thread according to ISO 68-1;
d) with diameter/pitch combinations according to ISO 261 and ISO 262;
e) with specified property classes, including proof load;
f) with different nut styles: thin nuts, regular nuts and high nuts;
g) with minimum height m ≥ 0,45D;
h) with a minimum outside diameter or width across flats s ≥ 1,45D (see Annex A);
i) able to mate with bolts, screws and studs with property classes according to ISO 898-1.
For hot dip galvanized nuts, see ISO 10684.
This part of ISO 898 does not specify requirements for properties such as:
— prevailing torque properties (see ISO 2320);
— torque/clamp force properties (see ISO 16047 for test method);
— weldability;
— corrosion resistance.
