M15 ASTM A453 18-8 Hex Hexagon Head Flange Metal Bolt Full Partial
Thread DIN6921
1,Description:
Stainless acid-resistant steel is referred to as stainless steel,
which is composed of two major parts of stainless steel and
acid-resistant steel. In short, the steel that can resist
atmospheric corrosion is called stainless steel, while the steel
that can resist corrosion by chemical media is called
acid-resistant steel.Generally speaking, the steel containing
chitin Wcr more than 12% has the characteristics of stainless
steel.Stainless steel according to the microstructure after heat
treatment can be divided into five categories: that is, ferrite
stainless steel, martensitic stainless steel, austenitic stainless
steel, austenitic - ferrite stainless steel and precipitation
carbonation stainless steel.
Because stainless steel has excellent corrosion resistance,
molding, compatibility and toughness in a wide range of
temperatures and other series of characteristics, so in the heavy
industry, light industry, household goods industry and building
decoration and other industries to obtain a wide range of
applications.
Flange bolt is composed of hexagonal head and flange, its "support
area and stress area word ratio" is greater than ordinary bolts, so
this bolt can withstand higher preload, anti-loose performance is
also better, so it is widely used in automotive engines, heavy
machinery and other products. The flange bolt is a bolt composed of
two parts: a hexagon head and a flange (the gasket under the
hexagon and the hexagon are fixed into one) and a screw (a cylinder
with external threads)
surface color category: according to different needs, the surface
has plated white, army green, color yellow, corrosion resistant
Dacromet.
flange type: according to the use of flange bolts in different
positions, the size of the plate requirements are different
It needs to be combined with the nut to fasten the parts connecting
two through holes, so the bolt connection is a detachable
connection.
hexagonal head type: one is flat brain, the other is concave brain.
2,Applications:
The application range of bolts is: electronic products, mechanical
products, digital products, power equipment, mechanical and
electrical machinery products. Bolts are also used in ships,
vehicles, hydraulic projects, and even chemical experiments. Bolts
are used in a lot of places anyway. Such as the precision bolts
used in digital products. Miniature bolts for DVDS, cameras,
glasses, clocks, electronics, etc. General bolts for televisions,
electrical products, Musical Instruments, furniture, etc.; For
projects, buildings and Bridges, large bolts and nuts are used;
Transportation equipment, aircraft, trams, cars, etc., are used
with large and small bolts. Bolts have important tasks in industry,
and as long as there is industry on Earth, the function of bolts
will always be important.
| Applications |
|
|
| car | In high-strength applications such as automotive engines,
heavy-duty machinery, and bridge construction, they are preferred
for their larger support area and better anti-loosening
performance. |
|
|
| mechanical | Mechanical, electronic, automotive, construction and other fields,
used to connect various mechanical parts, circuit boards, engines,
transmissions, building structures, etc |
| energy | For the energy industry, brackets and fixtures used to connect
power generation equipment and transmission lines
|
| architectural | In the field of construction engineering, shipbuilding, and
petrochemical industry, it is used to connect building structures,
improve the navigation safety and stability of ships, and ensure
the safety and stability of petrochemical equipment |
3,Specifications:
| material |
| aluminium | Aluminum has excellent thermal and electrical conductivity.
However, aluminum is naturally soft and may produce gelatinous
buildup after processing. If not properly operated, it is difficult
to cut during processing. |
|
|
| titanium | Edm machining is well suited for titanium because the process can
withstand the viscosity of this alloy and break down lengthy chips.
However, deionized water is needed as a medium to help control the
heat generated during processing.
|
|
|
| steel | Steel is a very strong metal, and many manufacturers tend to use
wire cutting machines instead of CNC machines for machining complex
steel features. However, this material generates a lot of heat, so
necessary precautions need to be taken. |
|
|
| brass | Brass has a high tensile strength and is easy to cut by machine.
But the cutting speed should be slow because it is a soft metal. |

4,Feature Advantage:
Ordinary bolt head is very thick, difficult to deform, if vibration
occurs after good, but also need to re-tighten; The flange with a
thin part, can be slightly deformed, can be locked more firmly.
There is also the fact that if it goes to the hole, the ordinary
bolt can not use the tool, the head of the flange bolt is smaller,
the following flange plate also plays a fastening role, but it can
be used on the special tool to the hole, and the hexagonal bolt is
about the same principle. Another is the flange top flat pad to
use, in the softer, non-wear-resistant material is safer, will not
cause perforation
