<p>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.</p>
<p>This document applies to nuts:</p>
<p>— with ISO metric thread (see ISO 68-1),</p>
<p>— with diameter/pitch combinations according to ISO 261 and ISO 262,</p>
<p>— with coarse pitch thread M5 to M39, and fine pitch thread M8×1 to M39×3,</p>
<p>— with thread tolerances according to ISO 965-1, ISO 965-2 or ISO 965-5,</p>
<p>— with specified property classes 04, 05, 5, 6, 8, 10 and 12 including proof load,</p>
<p>— of three different nut styles (see 5.1): regular nuts (style 1), high nuts (style 2) and thin nuts (style 0),</p>
<p>— with a minimum outside diameter or width across flats <em>s</em> ≥ 1,45<em>D</em>,</p>
<p>— able to mate with bolts, screws and studs with property classes in accordance with ISO 898-1 (see Annex B), and</p>
<p>— intended to be used in applications ranging from –50 °C to +150 °C, or up to +300 °C.</p>
<p>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).</p>
<p>For additional specifications applicable to hot dip galvanized nuts, see ISO 10684.</p>
<p>For nuts designed for particular applications, see ISO/TR 16224.</p>
<p>This document does not specify requirements for functional properties such as:</p>
<p>— prevailing torque properties (see ISO 2320),</p>
<p>— torque/clamp force properties (see ISO 16047 for test method),</p>
<p>— weldability, or</p>
<p>— corrosion resistance.</p>
