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