What are bolt classifications and bolt applications
there are many mechanical parts in our life. Bolts are a kind of
mechanical parts, which are mainly
used together with nuts and belong to a kind of fixed parts. There
are many kinds of bolts with
different specifications, which need to be used with different
nuts. Most bolts are made of stainless
steel, and some bolts are made of other metals. Bolts are not only
a kind of hardware parts, but
also a common hardware accessories. Here is the classification of
bolts.
I. classification
according to the stress mode of connection: ordinary and reamed
holes. According to the shape
of the head: hexagonal, round, square, countersunk, etc. The
hexagonal head is the most commonly
used. Generally, countersunk head is used where connection is
required.
widely used
1. Riding bolt
the English name of riding bolt is U-bolt. It is a non-standard
part and its shape is U-shaped, so it is
also called U-bolt. There are threads at both ends and can be
combined with nut. It is mainly used
to fix tubular objects such as water pipe or sheet objects such as
leaf spring of automobile. It is
called riding bolt because its way of fixing objects is like people
riding on a horse.
2. It is divided into full thread and non full thread according to
the thread length.
according to the thread profile, it is divided into coarse tooth
and fine tooth. The coarse tooth profile
is not displayed in the mark of the bolt.
bolts are divided into eight grades according to performance
grades: 3.6, 4.8, 5.6, 5.8, 8.8, 9.8, 10.9
and 12.9. Bolts above grade 8.8 (including grade 8.8) are made of
low-carbon alloy steel or medium
carbon steel and heat treated (quenched + tempered). They are
generally referred to as
high-strength bolts, and bolts below grade 8.8 (excluding grade
8.8) are generally referred to as
ordinary bolts.
3. Ordinary bolts can be divided into three grades A, B and C
according to the manufacturing
accuracy. Grades A and B are refined bolts and grade C is rough
bolts. Unless otherwise specified,
connecting bolts for steel structures are generally ordinary coarse
grade C bolts.
there are differences in the processing methods of different
levels, and the corresponding
processing methods are usually as follows:
① the bolt rod of Grade A and B bolts is machined by lathe, with
smooth surface and accurate size.
Its material performance grade is grade 8.8, complex fabrication
and installation, high price and
rarely used;
② grade C bolts are made of unprocessed round steel, the size is
not accurate enough, and their
material performance grade is grade 4.6 or 4.8. Large deformation
during shear connection, but
convenient installation and low production cost. It is mostly used
for tensile connection or temporary
fixation during installation.
the above is the classification introduction of bolts. We can also
go directly to hardware stores or
supermarkets to buy bolts. Bolts are available in many places, so
we don't have to find
manufacturers to make them. The fixing effect of bolts is
relatively good, but different types of bolts
have different purposes. When selecting bolts, they also need to be
selected according to the
mechanical properties. The fixing bolts need to be used for parts
with different mechanical properties.
