1.1 This specification2 covers a variety of carbon, alloy, and martensitic stainless steel nuts in the size range8201;1/4 through 4 in. and metric M6 through M100 nominal. It also covers austenitic stainless steel nuts in the size range8201;1/4 in. and M6 nominal and above. These nuts are intended for high-pressure or high-temperature service, or both. Grade substitutions without the purchaser's permission are not allowed. 1.2 Bars from which the nuts are made shall be hot-wrought. The material may be further processed by centerless grinding or by cold drawing. Austenitic stainless steel may be solution annealed or annealed and strain-hardened. When annealed and strain hardened austenitic stainless steel is ordered in accordance with Supplementary Requirement S1, the purchaser should take special care to ensure that 8.2.2, Supplementary Requirement S1, and Appendix X1 are thoroughly understood. 1.3 Supplementary requirements of an optional nature are provided. These shall apply only when specified in the inquiry, contract, and order. 1.4 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable“ M” specification designation (SI units), the material shall be furnished to inch-pound units. 1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Within the text, the SI units are shown in brackets.

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.
