This International Standard lays down the terminology and nomenclature of bolts, screws, nuts and accessories in English, French, Russian, German, Italian and Spanish, recommended for use unless otherwise specified in the appropriate product standard.
At present, not all of the fasteners and accessories listed are covered by ISO publications. For the main part, the items have been selected from existing national standards. Also included are obsolescent types (those being used up from stock) in order that their terminology may be standardized at the same time.
The drawings are essentially diagram-matic, in particular those showing bolts and screws having special charac-teristics dealt with, for example, in clauses 18 and 19. However, it is recommended that these drawings be used as a base whenever possible.
NOTE — The equivalent terms in German, Italian and Spanish have been included at the request of Technical Committee ISO/TC 2 and are published under the responsibility of the member bodies for Germany, F.R. (DIN), Italy (UNI) andSpain (IRANOR) respectively. However, only the terms given in the three official ISO languages (English, French and Russian) can be considered as ISO terms.
