17、bolts with flanges, small series, of product grade A (except the driving feature which is according to product grade B), with threads from M5 up to and including M16, and property classes 8.8 to 10.9 and A2-70. If, in special cases, specifications other than those listed in this International Standa
18、rd are required, they can be selected from existing International Standards, for example ISO 261, ISO 888, ISO 898-1, ISO 965-2 and ISO 3506-1. 2 Normative references The following referenced documents are indispensable for the application of this document.
