Common points between self-tapping screws and self-drilling screws
The body is threaded and can be self-tapping.
The difference between self-tapping screws and self-drilling screws
1. Difference in use: Self-tapping screws are used on materials with low hardness such as non-metal or soft metal (such as color steel plate). It can be fixed on the material to be fixed by its own thread. The fixed body "drills, squeezes, presses, and taps" the corresponding threads to make them closely match each other. The tail screw is mainly used for fixing the steel tile of the steel structure, fixing on the thin plate and the like.
2. the difference in usage: when the self-tapping screw is screwed in, the corresponding internal thread is formed by extrusion. No need to punch, tap, complete the operation at one time, but it is not recommended to drill multiple times, which is easy to damage the hole or slip. When the tail screw is used, it does not need auxiliary machining, and can be drilled, tapped and locked directly on the material, which greatly saves the installation time.
3. the difference in appearance: self-tapping screws are generally pointed, coarse thread, hard texture, with a certain degree of taper, in order to "self-tapping", but can not drill, but the head of the screw thread There is a drill bit that can be drilled.
