If we are going to use a screw, then the first thing we need to do is to understand the performance of the screw, and its characteristics, so that we can use the screw in the right place. Because there are many types of screws, the performance of each type of screw is different among these screws, so that the screws have different uses. In order to avoid our mistaken use of screws, we must have a certain understanding of the performance of the screws so that we can use the screws in the most correct place.
First of all, let's take a look at the self-tapping screws, which have 0.8mm to 12mm self-tapping screws for self-tapping screws. For this kind of screw is generally with a high degree of hardness, self-tapping screws to be screwed into the test, is to screw into a test plate, and then check the hardness of the screw is in line with the standard, if you need to analyze the standard Where is the problem? In order to find a solution.
There is also a self-drilling screw. As its name suggests, the screw tail generally shows the shape of a drill tail. The hardness of this screw is also very strong. Compared with ordinary screws, not only the ability to maintain is better, but also in the connection of objects. The effect is also very strong. For this type of screw, it is generally not required to perform auxiliary processing. You can directly drill a hole to lock the object directly above the object. Not only is it convenient to use, but it also greatly enhances the work. effectiveness. This type of self-drilling screw can be said to be the first choice for workers in various fields.
