Carbon steel, also known as carbon alloy steel, is a kind of iron-carbon alloy with a carbon content ranging from 0.0218% to 2.11%.
 
Carbon steel has the following characteristics and advantages:
 
1. Relatively low price: The cost is relatively economical.
2. Good mechanical properties: Possessing certain strength, hardness and toughness.
3. Good processability: Easy to carry out various processes such as forging, casting, and welding.
 
Its disadvantages mainly include relatively poor corrosion resistance.
 
Carbon steel is widely used in many fields, such as manufacturing mechanical parts, building structures, tools, etc. According to the different carbon contents, carbon steel can also be divided into low-carbon steel, medium-carbon steel and high-carbon steel, and they will also have differences in performance and uses.

Flat head screws mainly have the following characteristics:
 
In terms of appearance, its head is relatively flat and closely adheres to the mounting surface, which can make the surface after installation relatively smooth and flat.
 
In terms of function, flat head screws are more applicable in some cases where it is necessary to keep the mounting surface flat and beautiful or the space is relatively compact, such as the installation of precision instruments, electronic equipment, etc. The distribution of its fastening force is relatively uniform.
 
Compared with other types of screws, flat head screws are relatively less conspicuous and visually more concise. But at some specific angles, it may not be as easy to operate as round head screws and the like.
 
In addition, there are also various specification sizes of flat head screws to meet different installation requirements.
