scope:

Specifies the mechanical properties of nuts made from austenitic, martensitic and ferritic grades of corrosion-resistant stainless steels when tested at an ambient temperature range of 15 °C to 25 °C. Properties will vary at higher and lower temperature. It applies to nuts: - with nominal thread diameters up to and including 39 mm; - of triangular ISO metric threads with diameters and pitches according to ISO 68 and ISO 262; - of any shape provided; - with width across flats as specified in ISO 272; - with nominal heights greater then or equal to 0,5 d.
