Fasteners — Mechanical properties of fasteners made of carbon steel and alloy steel — Part 2: Nuts with specified property classes
| 분야 | ISO/TC 2/SC 12 : Fasteners with metric internal thread |
|---|---|
| 적용범위 | 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. |
