This International Standard specifies the characteristics of hexagon head bolts with threads from M1,6 up to
and including M64, of product grade A for threads M1,6 to M24 and nominal lengths up to and including 10d or
150 mm, whichever is the shorter, and product grade B for threads over M24 or nominal lengths over 10d or
150 mm, whichever is the shorter.
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, ISO 965-1,
ISO 3506-1, ISO 4753 and ISO 4759-1.
