Fasteners - Mechanical properties of fasteners made of carbon steel and alloy steel - Part 2: Nuts with specified property classes (ISO 898-2:2022)
SIST EN ISO 898-2:2022

This document specifies the mechanical and physical properties of nuts made of non-alloy steel or alloy steel, when tested at the ambient temperature range of 10 °C to 35 °C.
This document applies to nuts:
—    with ISO metric thread (see ISO 68-1),
—    with diameter/pitch combinations according to ISO 261 and ISO 262,
—    with coarse pitch thread M5 to M39, and fine pitch thread M8×1 to M39×3,
—    with thread tolerances according to ISO 965-1, ISO 965-2 or ISO 965-5,
—    with specified property classes 04, 05, 5, 6, 8, 10 and 12 including proof load,
—    of three different nut styles (see 5.1): regular nuts (style 1), high nuts (style 2) and thin nuts (style 0),
—    with a minimum outside diameter or width across flats s ≥ 1,45D,
—    able to mate with bolts, screws and studs with property classes in accordance with ISO 898-1 (see Annex B), and
—    intended to be used in applications ranging from –50 °C to +150 °C, or up to +300 °C.
WARNING — Nuts conforming to the requirements of this document are tested at the ambient temperature range of 10 °C to 35 °C and are used in applications ranging from –50 °C to +150 °C; however, these nuts are also used outside this range and up to +300 °C for specific applications. It is possible that they do not retain the specified mechanical and physical properties at lower and/or elevated temperatures. Therefore, it is the responsibility of the user to determine the appropriate choices based on the service environment conditions of the assembly (see also 7.1).
For additional specifications applicable to hot dip galvanized nuts, see ISO 10684.
For nuts designed for particular applications, see ISO/TR 16224.
This document does not specify requirements for functional properties such as:
—    prevailing torque properties (see ISO 2320),
—    torque/clamp force properties (see ISO 16047 for test method),
—    weldability, or
—    corrosion resistance.

Fasteners - Mechanical properties of corrosion-resistant stainless steel fasteners - Part 2: Nuts with specified grades and property classes (ISO 3506-2:2020)
SIST EN ISO 3506-2:2020

This document specifies the mechanical and physical properties of nuts, 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 nuts.
ISO 3506‑6 provides general rules and additional technical information on suitable stainless steels and their properties.
Nuts 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 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 fastener mechanical properties and clamped parts, and the corrosive service environment of the bolted joint.
NOTE 2  ISO 3506‑5[1] 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 nuts:
—     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 M5 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, including proof load,
—     with different nut styles: thin nuts, regular nuts and high nuts,
—     with a minimum nut height m ≥ 0,45D,
—     with a minimum outside diameter or width across flats s ≥ 1,45D (see Annex A),
—     of any shape, and
—     able to mate with bolts, screws and studs with property classes in accordance with ISO 3506‑1.
Stainless steel grades and property classes can be used for sizes outside the diameter limits of this document (i.e. for D < 5 mm or D > 39 mm), provided that all applicable chemical, mechanical and physical requirements are met.
This document does not specify requirements for functional properties such as:
—     torque/clamp force properties,
—     prevailing torque properties, or
—     weldability.

SIST EN ISO 898-3:2018

This document specifies mechanical and physical properties of flat washers, designed to be used in bolted joints in combination with bolts, screws, studs and nuts with a specified property class in accordance with ISO 898‑1 and ISO 898‑2.
NOTE 1    These types of washers can also be used with other fasteners such as screws forming their own mating thread.
Washers that conform to the requirements of this document are evaluated at an ambient temperature range of 10 °C to 35 °C. They might not retain the specified mechanical and physical properties at elevated temperatures and/or lower temperatures.
NOTE 2    Washers conforming to the requirements of this document are used in applications ranging from −50 °C to +150 °C. Users are advised to consult an experienced fastener expert for temperatures outside this range and up to a maximum temperature of +300 °C when determining appropriate choices, or for critical applications.
This document is applicable to the following flat captive and non-captive washers made of carbon steel or alloy steel, with thickness from 0,2 mm to 12 mm:
—          plain washers (with or without knurls, ribs or chamfers);
—          square washers;
—          square hole washers;
