25、ard belongs to a complete group 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, ISO 4018 and ISO 8676); c) hexagon nuts (ISO 4032, ISO 4033, ISO
26、 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 flange (ISO 4161, ISO 7043, ISO 7044, ISO 10663, ISO 12125, ISO 12126
27、 and ISO 21670). EN ISO 8676:2011 (E) DIN EN ISO 8676:2011-07 41 Scope This International Standard specifies the characteristics of hexagon head screws with metric fine pitch thread with nominal thread diameters, d, from 8 mm to 64 mm, of product grade A for nominal thread diameters, d, from 8 mm to
28、 24 mm and nominal lengths, l, up to and including 10d or 150 mm, whichever is the shorter, and of product grade B for nominal thread diameters, d, over 24 mm or nominal lengths, l, over 10d or 150 mm, whichever is the shorter. If, in special cases, specifications other than those listed in this Int
29、ernational Standard are required, they can be selected from existing International Standards, for example ISO 724, ISO 888, ISO 898-1, ISO 965-1, ISO 3506-1, ISO 4753 and ISO 4759-1. It is intended that coarse thread screws according to ISO 4017 be the first choice. 2 Normative references The follow
