DIN EN ISO 4033:2013-04

This standard specifies the characteristics of hexagon high nuts (style 2), with threads from M5 up to and including M36, in product grade A for threads, D, up to and including M16 and product grade B for threads, D, above M16. 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 4033:2012 in which the International Standard ISO 4033:2012 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.
