[0008] Preferably, the shape of the drill bit is conical, and the angle of the drill bit is 30°.

[0009] Preferably, the proportion of the thread teeth on the rod is 70%.

[0010] Preferably, the outer wall of the rod part is provided with a plurality of through holes, and the plurality of through holes are distributed along the central axis of the rod part.

[0011] Compared with the prior art, the high-stability lightweight self-tapping and self-drilling wall panel nail has the following beneficial effects:

[0012] I. In use, by setting a special base diameter, the specific gravity is reduced by 3%, and the reduction of specific gravity means that the total weight of each product is reduced, so that in the case of the same weight, the increased number of wall panel nails can cover a larger construction range, avoiding additional procurement and time delay due to insufficient wall panel nails;

[0013] II. In use, the thread angle of 60° and the bevel angle of 30° provide good cutting performance, so that the wall panel nail can cut the material more effectively when drilling, reduces the drilling resistance, improves the self-tapping and self-drilling effect, optimizes the tapping speed, improves the construction efficiency, and is suitable for large-scale application. The screw head is designed in a horn shape to increase the contact area of the screw head and the wall surface, improve the stability and reliability of fastening, and the design of the cross slot facilitates the operation of the workers and improves the construction efficiency;

[0014] III. In use, the drill bit is conical in shape, and the angle of 30° makes it easy to penetrate various wall materials, which is beneficial to reduce the resistance in the drilling process, improve the drilling efficiency of the wall panel nail, ensure the smoothness of the construction process, and reduce the physical exertion during operation. By setting the thread tooth ratio to 70%, compared with the conventional wall panel nail, the thread tooth ratio is reduced, which is beneficial to the smoothness of the wall panel nail during drilling and reduces the resistance, thereby accelerating the tapping speed and improving the construction efficiency. At the same time, fewer thread teeth mean that the processing steps and difficulty in the manufacturing process are reduced, which is beneficial to reducing production costs and improving production efficiency. The through hole is beneficial to reducing the weight of the rod part, thereby reducing the overall weight of the wall panel nail, not only improving portability, but also reducing fatigue during long-term use and improving work efficiency.

[0022] By setting the special base diameter, the specific gravity is reduced by 3%, and the reduction of specific gravity means that the total weight of each product is reduced, so that in the case of the same weight, the increased number of wallboard nails can cover a larger construction range, avoiding additional procurement and time delay caused by insufficient wallboard nails.

[0023] As Figure 1 and Figure 3 shown, the angle of the thread tooth 4 is 60°, and the angle of the inclined surface of the thread tooth 4 is 30°.
