Large hexagon high strength bolt
The thread specification of large hexagon high-strength bolt is
m12-m30 (it can produce M12, M16,
M20, M22, M24, M27 and M30 thread specifications), the length is
35mm-260mm, the performance
grades are 8.8, 10.9 and 12.9, and the performance indexes comply
with GB / T 1228-2006, DIN
6914-2008, GB / T 18230.1-2000, GB / T 18230.2-2000, IFI 149-2000,
ISO 7411-1984, ISO 7412-
1984 Gost R 52644-2006 large hexagon high strength bolt.
The raw materials for the production of large hexagon high-strength
bolts are all high-quality steel
produced by domestic well-known large-scale steel manufacturers
that meet the provisions of
relevant material standards. They are precision manufactured by
international advanced professional
production equipment and undergo professional heat treatment
processing by advanced heat
treatment production lines. All production links are subject to
strict random inspection by the quality
inspection department to eliminate the emergence of unqualified
products from the source, Ensure
that all performance indexes of each large hexagon high-strength
bolt fully comply with the provisions
of product standards.
The inspection equipment is complete, the quality control is strict
and standardized, and the quality
inspection of finished products is strict; The large hexagon
high-strength bolts produced by our
company have excellent materials, strict inspection, stable quality
and reasonable price, and provide
product quality inspection certificates. Large hexagon
high-strength bolts of various specifications are
applied to many large-scale key projects at home and abroad; It has
long cooperated with many
well-known domestic steel structure engineering companies and
exported to more than ten countries
and regions such as Russia and Iran, which has been unanimously
recognized and praised by local
construction units and owners; Trusted by users everywhere! Welcome
all new and old customers of
large hexagon high-strength bolts to visit us! The hexagon head of
large hexagon high-strength bolt
is different from that of general external hexagon bolt. The size
of hexagon head of large hexagon
high-strength bolt is larger than that of ordinary hexagon bolt
products, so large hexagon
high-strength bolt can also be called large hexagon high-strength
bolt. Large hexagon high strength
bolts are mainly used for the construction of industrial and civil
buildings, railway bridges, highway
bridges, pipeline bridges, tower and mast structures, boiler
frames, boiler steel structures, long-span
industrial plants, high-rise civil buildings, various towers, light
steel structures, hoisting machinery and
other steel structure connection buildings. Each set of large
hexagon high-strength bolts includes one
high-strength large hexagon high-strength bolt GB / T 1228, one
high-strength nut GB / t1229 for steel
structure and two high-strength washers GB / t1230 for steel
structure, which are manufactured in the
same batch. The standards for large hexagon high strength bolts
include: GB / t1228-2006 large
hexagon high strength bolts, GB / t1229-2006 high strength large
hexagon nuts for steel structures,
GB / t1230-2006 high strength washers for steel structures, and GB
/ t1231-2006 technical conditions
for large hexagon high strength bolts, large hexagon nuts and
washers. When assembling the
connecting pair of large hexagon high-strength bolts, the chamfered
side of the washer under the bolt
head shall face the bolt head; Torque wrench is required for the
construction of large hexagon
high-strength bolt, which requires large operation space. It should
be completed in two parts: initial
tightening and final tightening. The construction is more
troublesome than torsional shear bolt; Quality
inspection also requires torque inspection, professional equipment
and quality inspection personnel.
