A nut with an ISO metric thread is marked on
one face or on one of the flats of the hexagon

the flat opposite the strength grade marking.
A clock face system is used as an alternative
method of indicating the strength grade. The
external chamfers or a face of the nut is marked

mark on a clock face to indicate the strength
grade.
