1,Description:

The tail of the screw is generally shown as the shape of drilling tail, the hardness of this screw is very strong, compared with ordinary screws, not only the ability to maintain better, the effect of connecting the object is very firm, for this performance of the screw, generally do not need auxiliary processing, you can directly drill a hole on the object directly to lock the object, not only very convenient to use, It can also greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of staff in various fields.

2,Applications:
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The main purpose is to make industrial products composed of a fixed body, in the use of teeth and teeth often can not be close, too hard to lock the screw head is broken, or poor dental lock is not tight and failed to meet the conditions of use, are precision problems. Screws are "quantity products", not hand-made artworks, in mass production, in order to achieve high precision and stable quality and popular price supply to consumers for the purpose. The accuracy of the screws is usually 6g (Class 2, the US specification "IFI" is 2A teeth), and the rough screws used in construction projects are 8g (Class 3, "IFI" is 1A teeth).

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:

 

The values of 4.8 and 8.8 are classified by performance. The higher the value, the better the performance. The differences between grade 4.8 and grade 8.8 bolts are as follows:

I. Methods of Distinction and Differentiation:

Grade 4.8 is generally called common bolts, among which grade 8.8 is called high-strength bolts.

2. 8.8 grade bolts are made of low-carbon alloy steel or medium carbon steel and have undergone heat treatment (quenching, tempering), while 4.8 grade bolts are not.

3. 4.8 grade bolts are made of unprocessed round steel, with less precise dimensions. They deform significantly during shear connections, but they are easy to install and have a low production cost. They are mostly used for tensile connections or temporary fixation during installation. The bolt rods of grade 8.8 bolts are processed by lathes, with smooth surfaces, precise dimensions, complex manufacturing and installation, and relatively high prices. They are rarely used.

Bolts are classified into eight grades according to their performance, namely 3.6, 4.8, 5.6, 5.8, 8.8, 9.8, 10.9 and 12.9.
