What is a self tapping and self drilling screw?

In many fields and industries, we often use self tapping and self drilling screws. If we only understand from the name, we can see some properties of this screw. Firstly, it can independently complete a fastener product for tapping and drilling, which is a category of hardware products. Secondly, in the process of developing and manufacturing it, different models will be matched with matching drill bits for the sharpening process of screw heads.

The common self tapping and self drilling screws on the market are mainly composed of three parts: the head, the rod, and the end of the tail. There are thousands of styles for the head alone, including round head, flat round head, pan head, countersunk head, hexagonal head, and so on. If specific analysis is conducted, the round head includes elliptical round head, flat round head, convex round head, etc. It can't help but feel magical: "A small screw, sometimes easily overlooked, has a thousand different shapes, in order to adapt to the connection and fixation of different materials! There is a lot of energy in the small body!"

Coincidentally, because self tapping and self drilling screws do not require pre reserved holes, we use professional electric drills for construction, completing drilling, tapping, fixing, and locking in one go. So it is mainly used for connecting or fixing between some thinner sheets. In daily life, the connection between color steel plates and between color steel plates, purlins, and walls can be easily achieved. Its penetration ability generally needs to be controlled between 6mm and 12mm.
