DIN National standards (DIN) will be/have been largely replaced by international/European standards. DIN standards are still valid for products having no ISO or EN standards. As far as possible, existing ISO standards should generally be adopted as EN standards without any changes. The difference between ISO and EN standards is that EN standards following the decision of the European Council have to be adopted and implemented in the member states as national standards without any changes and without delay – and the corresponding national standards have to be withdrawn at the same time.Bhalla Fasteners is the leading manufacturer, supplier and exporter of din 558 bolts and supply to USA,UK,Poland,Germany,France,Italy,Finland,Netherlands.
Din Hexagon head bolts standards have been withdrawn years ago. The successor ISO standards largely comply with the DIN standards withdrawn. Therefore, there are normally no restrictions on use. Basically the difference comes only for the dimensions M10, M12, M14 and M22 where din 933 and its ISO equivalent 4017 and Din 931 and its ISO 4014 are different. The dimensions for the widths across flats are different in these sizes which Bhalla Fasteners which is the leading manufacturer, exporter and supplier of din558 to USA ,UK, Poland ,Germany ,Italy and Bulgaria manufacturers keeping in mind these standards .So in sizes M10, M12, M14 the across flat width is slightly smaller (1mm) and M22 size the across flat width is 2mm larger.
