1. Scope
1.1 This specification covers chemical and mechanical requirements for eight property classes of hex and hex-flange carbon and alloy steel nuts for general structural and mechanical uses on bolts, studs, and other externally threaded parts.
NOTE 1—Requirements for the four classes 5, 9, 10, and 12 are essentially identical with requirements given for these classes in ISO898/II. Requirements for Classes 8S and 10S are essentially identical with requirements in an ISO 4775 Hexagon Nuts for High-Strength Structural Bolting with Large Width Across Flats, Product Grade B, Property Classes8 and 10. Classes 8S3 and 10S3 are not recognized in ISO standards.
2. Materials and Manufacture
2.1 Steel for nuts shall be made by the open-hearth, basic-oxygen, or electric-furnace process.
2.2 Nuts may be made cold or hot by forming, pressing, or punching, or may be machined from bar stock.
2.3 Classes 10, 12, 10S, and 10S3 nuts shall be heat treated by quenching in a liquid medium from a temperature above the transformation temperature and tempering at a temperature of at least 425°C.
2.4 Classes 8S and 8S3 nuts made of any steel permitted for these classes may be heat treated by quenching in a liquid medium from a temperature above the transformation temperature and tempering at a temperature of at least 425°C.
2.5 Class 8S nuts made of steel having a carbon content not exceeding 0.20 %, phosphorus not exceeding 0.04 %, and sulfur not exceeding 0.05 % by heat analysis may be heat treated by quenching in a liquid medium from a temperature above the transformation temperature and need not be tempered.
2.6 Threads shall be formed, tapped, or machined.
2.7 Zinc Coatings, Hot-Dip and Mechanically Deposited:
2.7.1 When zinc-coated fasteners are required, the purchaser shall specify the zinc coating process, for example, hot-dip, mechanically deposited, or no preference.
2.7.2 When hot-dip is specified, the fasteners shall be zinc-coated by the hot-dip process in accordance with the requirements of Class C of Specification A 153/A 153M.
2.7.3 Hot-dip zinc coated nuts shall be tapped after zinc coating.
2.7.4 Mechanically deposited zinc-coated nuts for assembly with mechanically deposited zinc-coated bolts shall be tapped oversize prior to zinc coating and need not be retapped afterwards.
2.8 Hot-dip and mechanically deposited zinc-coated Class 10S nuts shall be provided with an additional lubricant that shall be clean and dry to the touch.
