If we are going to use a screw, the first thing we have to do is to understand the performance of the screw, that is its characteristics, so that we can use the screw in the most correct place. Because there are many types of screws, among these screws, the performance of each type of screw is different, so the screws have different uses. In order to avoid our wrong use of screws, we must have a certain understanding of the performance of screws, so that we can use the screws in the most correct place.
First, let's take a look at self-tapping screws. For self-tapping screws with a diameter of 0.8mm to 12mm . For this type of screws, they generally have a high hardness. Self-tapping screws have to undergo a screw-in test, which is to screw the screw into a test plate, and then check whether the hardness of the screw meets the standard. If it does not meet the standard, you need to analyze it. Where is the problem ? To find a solution.
There is also a self-drilling screw. As the name suggests, the tail of the screw generally shows the shape of a tail. The hardness of this kind of screw is also very strong. Compared with ordinary screws, it not only has better maintenance ability, but also connects objects. The effect is also very strong. For screws with this performance, auxiliary processing is generally not required. You can directly drill a hole on the object to lock the object. Not only is it very convenient to use, but it can also greatly improve the work. efficient. This kind of self-drilling screw can be said to be the first choice of workers in various fields.
From the above, we can find that it is very important for us to understand the performance of various screws when using screws.
