Firstly, we need to clarify the concept of drilling screws. Self drilling screw is a special type of screw with a drill bit at the end,

which can directly drill holes on the material during tightening, achieving fast and efficient tightening. This type of screw is

usually used for connecting and fixing materials such as metal, wood, plastic, etc.

The following are several significant advantages of self drilling screws:

1. Strong tightening force: The drill tail screw, through its own special structure, can form strong friction force in the fixed material
2. during tightening, thereby providing a stable tightening effect. This tightening force can maintain stability in various environments
3. and materials, ensuring the safety of the connection.
4.  

2. Corrosion resistance: Drilled tail screws usually use surface treatment processes such as galvanizing and chromium plating,

which have strong corrosion resistance. This enables them to maintain superior performance in harsh environments such as acid,

alkali, and humidity, greatly extending their service life.

3. Efficient cutting function: The drilling screw adopts an efficient cutting principle in its design, allowing it to quickly drill holes in

the fixed material during the tightening process. This cutting function not only improves work efficiency, but also reduces material

damage and the generation of debris.

4. Reliable connection: The drill tail screw can form a reliable locking state when tightened, effectively avoiding loosening and

detachment. This reliable connection characteristic allows the drill tail screw to maintain stability in various vibration and impact

environments.

5. Environmentally friendly: Drilled screws can reduce the generation of waste during use, which is beneficial for environmental

protection. Compared with other types of screws, drilling screws do not require pre drilling or tapping, reducing the generation

of processing waste and tool wear. In addition, the corrosion resistance and environmentally friend
