If we are going to use a screw, then the first thing we need to do is to understand the performance of this screw, which is its characteristics, so that we can use the screw in the most correct place. Because there are many types of screws, the performance of each of these screws is different, so the screws have different uses. In order to avoid the wrong 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 accurate place. First of all, let's take a look at the self-tapping screws, which have self-tapping screws with a diameter of 0.8mm to 12mm. For these types of screws, they are generally of high hardness. The self-tapping screws must be screwed into the test version, and the screws are screwed into a test version. Then the hardness of the screws is checked to meet the standard. If it is not standard, it needs to be analyzed. Where is the problem? So find a solution. Another type is the tail screw. As the name implies, the tail of the screw is generally in the shape of a drill tail. The hardness of this screw is also very strong. Compared with ordinary screws, it is not only better to maintain, but also in connecting objects. The effect is also very strong. For this kind of performance, the screws generally do not need auxiliary processing. You can directly drill a hole into the object directly on the object, which is not only very convenient to use, but also greatly improves the work. effectiveness. This type of self-drilling screw is the first choice for workers in various fields.
From the above we can find that we know the performance of various screws when using screws.
