Stainless Steel A2 A4 Butterfly Wing Machine Screw With Wing Nut
DIN316
1,Description:
There are many names for bolts, and everyone's name may be
different, some people are called screws, some people are called
bolts, and some people are called fasteners. Although there are so
many names, but the meaning is the same, are bolts. Bolt is a
general term for fasteners. The bolt is a tool to tighten the parts
step by step using the physical and mathematical principles of the
inclined plane circular rotation and friction force of the object.
2,Applications:
Bolts are indispensable in daily life and industrial production and
manufacturing, and bolts are also known as industrial meters. It
can be seen that the use of bolts is wide.
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:
Bolt market competition is fierce, to brand management. In the past
10 years, the speed of development of China's bolts has attracted
the attention of the world, which has surprised developed countries
at the same time, but also let them find a new type of large
market, and multinational companies have entered. When the domestic
bolt enterprises suddenly feel so difficult to survive in the
market, strong competitors have blossomed everywhere. In today's
China's bolt market, some small and medium-sized bolt enterprises
manufacture a large number of ordinary standard parts, which does
not really bring core competitiveness to enterprises, but is
subject to changes in raw materials, labor costs and other
conditions. From 4.8 to 6.8 low strength, or 8.8 to 12.9 high
strength bolts, China's bolt production technology level will be
basically close to the world's advanced level, mainly for ordinary
standard parts and low and medium grade special, shaped bolts,
large quantity and low price. Generally, low-grade products flooded
the dominant market, high-grade, high-precision, high-strength
bolts have a small part of the need to import, product import unit
price and bid ratio gap of about 6 times.
