Grade12.9

Screws
are
mostly
used
after
installation,
the
surface
of
the
parts
can
not
be
raised,
and
the
fastened
parts
have
two
thicknesses,
the
so-called
thick,
which
means
that
the
thickness
of
the
fastened
part
is
greater
than
the
thickness
of
the
head
of
the
countersunk
screw
Thickness.
After
the
screw
is
tightened,
there
is
still
a
part
of
the
screw
thread
that
does
not
enter
the
threaded
hole.
In
this
case,
the
countersunk
screw
can
definitely
be
tightened.
There
is
usually
another
case,
that
is,
the
thickness
of
the
fastened
parts
is
less
than
the
height
of
the
head
of
the
countersunk
head
screw,
which
is
common
in
sheet
metal
parts
in
mechanical
equipment,
such
as
the
connection
of
the
hinge
of
the
chassis
and
the
door
and
the
box;
the
sheet
metal
of
the
equipment
The
connection
between
the
cover
and
the
equipment,
etc.
Due
to
the
small
thickness
of
the
part,
the
screw
through
hole
of
the
fastened
sheet
metal
part
has
become
a
conical
hole
completely.
In
this
case,
when
the
countersunk
screw
is
tightened,
the
screw
head
is
not
a
conical
surface
to
compress
the
sheet
metal
part.
,
But
the
bottom
of
the
screw
head
and
the
top
of
the
threaded
hole
are
squeezed.
Although
the
screw
feels
that
the
screw
is
tightened,
the
sheet
metal
part
is
stuck
instead
of
being
pressed.
In
this
case,
although
the
screw
feels
that
the
screw
is
tightened,
the
sheet
metal
The
gold
piece
is
indeed
not
tightened.
This
is
a
very
common
situation.
