The series comprises: a) hexagon head bolts (ISO 4
22、014, 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 4034, ISO 4035, ISO 4036, ISO 8673, ISO 8674 and ISO 8675); d) hexagon flange bolts (ISO 4162, ISO 8100, ISO 8102 and ISO 8104); e) hexagon flange screws;1) f) he
23、xagon flange nuts (ISO 4161, ISO 7043 and ISO 7044); g) structural bolting (ISO 4775 and ISO 7411 to ISO 7417). 1 Scope and field of application This International Standard gives specifications for hexagon nuts, style 1, with thread diameters from M1,6 to M64 inclusive, with product grade A for size
24、s d u M16 and product grade B for sizes d M16. If, in special cases, specifications other than those listed in this International Standard are required, they should be selected from existing International Standards, e.g. ISO 261, ISO 898-2, ISO 965, ISO 4759-1.
