DIN 934

DIN 934 Field of Application

This standard outlines the specifications for hexagon nuts ranging from size M1 to M160. Nuts up to M16 fall under product grade A, while those above M16 are categorized as product grade B. In cases where specific requirements differ from those in this standard—such as property class—nuts should be chosen based on the appropriate applicable standards.
