Hexagon nuts complying with the DIN 934 standard cannot support test loads as per DIN EN ISO 898-2.
- The strength class designation has two vertical bars added before and after the strength code to differentiate.
DIN 934 has been withdrawn and replaced by ISO 4032/8673. There is no similarity (nominal Ø changed | Some nut heights changed | Width across flats changed for M10, M12, M14, M22 | ISO 4032 for standard thread | ISO 8673 for fine thread).
