What is DIN 934 ?

Din 934 is the standard for Hexagon nuts with metric coarse and fine pitch thread - There are two product classes A (up to M16)  and B (> M16)

DIN stands for "Deutsches Institut für Normung", meaning "German institute for standardisation" and is widely accepted globally, though many are not superseded by ISO standards.

Although the standard has now been withdrawn it is still very widely used. The new standards are DIN EN ISO 4032 and DIN EN ISO 8673 respectively and are interchangeable
