This International Standard specifies the characteristics of chamfered hexagon thin nuts, with threads
from M1,6 up to and including M64, with product grade A for threads d < M16 and product grade B for
threads 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, for example
ISO 724,
ISO 898-2,
ISO 965-1,
ISO 3506-2
and ISO 4759-1.
