Stainless steel drill tail screws are mainly used in indoor and outdoor installations such as metal light compartments and plastic steel doors and windows; Metal steel plate, galvanized steel plate, engineering installation; Installation of channel steel, iron plate and other metal materials in combination; Installation of assembly projects such as container containers, shipbuilding, refrigeration equipment, and environmental engineering. What are the characteristics and advantages of stainless steel drill tail screws, which are so widely used?

Stainless steel drill tail screws have the following characteristics:

A. Drilling, tapping, and locking are completed in one go, with strong adhesion;

B. Save construction time and improve work efficiency;

C. Professional manufacturing, quality assurance.

The main materials for stainless steel drill tail screws are SUS410; SUS201; SUS304; SUS316 has specifications of 3.5 (6 #), 3.9 (7 #), 4.2 (8 #), 4.8 (10 #), 5.5 (12 #), and 6.3 (14 #). Its length mainly includes 13-50 of (3.5; 3.9; 4.2; 4.8), 16-165 of (5.5), and 16-165 of (6.3).

According to the different head types, the names of stainless steel drilling screws mainly include: hexagonal head drilling tail, pan head drilling tail, countersunk head drilling tail, round head Huasi drilling tail, and special customized drilling tail.

Stainless steel drill tail screws with different materials and diameters have different usage ranges, and if they exceed the usage range, they may fail to penetrate or break the head. The following are the usage ranges of stainless steel drill tail screws of different specifications.

1、 Scope of use of 304 and 316 stainless steel drill tail screws

The drilling tail of 304 and 316 can only drill aluminum alloy plates. When drilling aluminum alloy plates, the speed of the electric drill should not be too fast. If the speed is too fast, the temperature will be high, and the aluminum chips can easily dissolve. After the aluminum chips dissolve, they will stick to the teeth of the drilling tail screw, causing the aluminum chips to not be easily discharged, leading to the phenomenon of not being able to drill. At this time, if the speed of the electric drill is further increased, the phenomenon of broken ends will occur.

1. The specification of the # 6 (3.5) diameter drill tail No. 2 ensures that it can penetrate 2.5mm thick aluminum alloy plate;

2. The specification of the # 8 (4.2) diameter drill tail No. 2 ensures that it can penetrate a 3mm thick aluminum alloy plate;

3. The diameter of the # 10 (4.8) drill tail and the specification of the # 3 drill tail ensure that it can penetrate 4.5mm thick aluminum alloy plate;

4. The size of the # 12 (5.5) diameter drill tail and the # 3 tail ensure that it can penetrate a 6mm thick aluminum alloy plate;

5. The size of the # 14 (6.3) diameter drill tail and the # 3 tail ensure that it can penetrate an 8mm thick aluminum alloy plate.

2、 410 material stainless steel drill tail screw Scope of use:

1. The size of the # 6 (3.5) diameter drill tail No. 2 tail ensures that it can penetrate 2.5mm thick carbon steel plates (iron plates), and the 2.6-5mm thick carbon steel plates and stainless steel plates need to be specially customized.

2. The size of the # 8 (4.2) diameter drill tail No. 2 tail ensures that it can penetrate 3mm thick carbon steel plates (iron plates), while the 3.1-7mm thick carbon steel plates and stainless steel plates require special customization.

3. Diameter # 10 (4.8)
