DIN EN ISO 8673:2013-04

This International Standard specifies the geometry of hexagon nuts with nominal thread diameter from 8 mm up to and including 64 mm and the mechanical properties of hexagon regular nuts (style 1) with metric fine pitch thread in product grade A for nominal thread diameter, D, up to and including 16 mm and in product grade B for nominal diameter, D, above 16 mm and up to and including 39 mm. In this revised version the normative references are now undated in order to facilitate the unequivocal use of each currently applicable version of a standard. Moreover, the content of the standard has been brought in line with the revised ISO 898-2. This standard is identical to the European Standard EN ISO 8673:2012 in which the International Standard ISO 8673:2012 was adopted without any modifications. This standard has been prepared by ISO/TC 2 "Fasteners" in collaboration with CEN/TC 185 "Fasteners", both secretariats of which are held by DIN. The responsible German standardization committee is Working Committee NA 067-00-03 AA "Verbindungselemente mit metrischem Innengewinde" ("Fasteners with metric internal thread") of the Fasteners Standards Committee (FMV) at DIN.
