23、E) DIN EN ISO 4018:2011-07 Introduction This International Standard belongs to a complete family of product standards developed by ISO on external hexagon drive fasteners. It comprises the following: a) hexagon head bolts (ISO 4014, ISO 4015, ISO 4016 and ISO 8765); b) hexagon head screws (ISO 4017,
24、 ISO 4018 and ISO 8676); c) hexagon nuts (ISO 4032, ISO 4033, ISO 4034, ISO 4035, ISO 4036, ISO 7040, ISO 7041, ISO 7042, ISO 7719, ISO 7720, ISO 8673, ISO 8674, ISO 8675, ISO 10511, ISO 10512 and ISO 10513); d) hexagon bolts with flange (ISO 4162, ISO 15071 and ISO 15072); e) hexagon nuts with flan
25、ge (ISO 4161, ISO 7043, ISO 7044, ISO 10663, ISO 12125, ISO 12126 and ISO 21670). 4EN ISO 4018:2011 (E) DIN EN ISO 4018:2011-07 1 Scope This International Standard specifies the characteristics of hexagon head screws with threads from M5 up to and including M64, of product grade C. NOTE This type of
26、 product is the same as that covered by ISO 4016 with the exception of threading up to head. If, in special cases, specifications other than those listed in this International Standard are required, they can be selected from existing International Standards, for example ISO 724, ISO 888, ISO 898-1,
27、ISO 965-1 and ISO 4759-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
