26、ndorsement notice The text of ISO 10512:2012 has been approved by CEN as a EN ISO 10512:2012 without any modification. “Fasteners”3DIN EN ISO 10512:2013-05 EN ISO 10512:2012 (E) 1 ScopeThis International Standard specifies the characteristics of prevailing torque type hexagon regular nuts (with non-
27、metallic insert) with metric fine pitch thread with nominal thread diameters, D, from 8 mm up to and including 36 mm, in product grade A for sizes D up to and including 16 mm and product grade B for sizes D above 16 mm, and with property classes 6, 8 and 10.If other specifications are required, they
28、 can be selected from existing International Standards, for example ISO 261, ISO 724, ISO 898-2, ISO 965-2, ISO 2320 and ISO 4759-1.NOTE 1 The dimensions of the nuts correspond to those given in ISO 8673 plus prevailing torque feature.NOTE 2 As there is an insufficient nut height due to the fine pit
29、ch thread, there is a higher probability of nut thread stripping. Hence, high nuts according to ISO 7041 are preferably used.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable to its application.
