If we are going to use a screw, what should we first to do is to understand the performance of screw, that is its characteristics. So we can put the screw in the right place. Because there are many kinds of screws and the performance of each kind of screw is not the same, the screw has different use. In order to avoid using screws wrongly, we must have a certain understanding of the performance of screw.

First of all, we learn about the self tapping screw. Self tapping screw has the diameter from 0.8mm to12mm. For this type of screws, they are usually with high hardness. Self tapping screw should pass the screw-in test. That is, twisting the screw  into a piece of beta, and then testing the hardness of screw to look whether it is in line with the standard. If it is not in line with the standard, we need to analyze what's the problem and find a solution.

Another is the self drilling screw. Just as its name implies, the tail of screw generally show the shape of drill tail. The hardness of the screw is also very strong. Compared with ordinary screws, not only the ability of maintain is good, but also the effect is very strong in the connection object aspects. For this performance of screw, it is generally do not need to assist processing. It can be said that the drilling screw is the first selection of personnel in all fields.

From the above, we can see it is very important to understand the performance of all kinds of screw. Dongguan King-Tower Hardware Co., Ltd is one of the largest enterprises to produce tight firmware in Mainland China. China screw manufacturer choose King-Tower.
