Carriage
Bolts
A
carriage
bolt
(also
called
coach
bolt and
round-head
square-neck
bolt.
Carriage
Bolt is
a form
of bolt
used to
fasten
metal to
metal or
metal to
wood.
The
carriage
bolt was
devised
for use
through
an iron
strengthening
plate on
either
side of
a wooden
beam,
the
squared
part of
the bolt
fitting
into a
square
hole in
the
ironwork.
It is
common
to use a
carriage
bolt to
bare
timber,
the
square
section
giving
enough
grip to
prevent
rotation.
The
carriage
bolt is
used
extensively
in
security
fixings,
such as
locks
and
hinges,
where
the bolt
must be
removable
from one
side
only.
The
smooth,
domed
head and
square
nut
below
prevent
the
carriage
bolt
from
being
unlocked
from the
insecure
side.
Use a
Carriage
Bolt
Carriage
bolts
are
ideal
for
fastening
wood to
metal.
Alternatively,
carriage
bolts
can also
be used
to
fasten
two
pieces
of wood
together.
Some
specialty
versions
of
carriage
bolts
allow
for the
effective
fastening
of two
separate
metal
components.
Furthermore,
they can
be used
in a
variety
of
different
industries
including
the
following:
- Water
conservation
and
treatment
industry,
-
Railroad
industry,
-
Farming
industry,
and
- Mining
industry,
to name
a few.
Step
Bolts
Step
bolts
are
similar
to
carriage
bolts in
that
they
both
have a
square
shoulder
and a
larger
bearing
surface.
Step
bolts,
however,
have a
larger
and
lower-profile
with a
round
head,
creating
a smooth
surface.
The
larger
heads
also
make it
more
difficult
pull
through
soft
materials.
