What are the characteristics of self-tapping screws?

2023-07-30

Self-tapping screws, as the name implies, are screws that tap themselves. Compared with ordinary screws, self-tapping screws have drill bits, which can be screwed in without machining screw holes. At the same time, tap yourself. It is mainly used for edge joining and fixing of some thinner plates. So what are the characteristics of self-tapping screws?

1. What are the characteristics of self-tapping screws - strong corrosion resistance

The self-tapping screw itself has strong corrosion resistance, and the added rubber sealing ring makes the screw impervious to water and rust no matter it is exposed outdoors or in a relatively humid environment.

2. What are the characteristics of self-tapping screws - the scope of use is small

Self-tapping screws are also called wood screws, which are suitable for wood materials. In addition, the screws are small and manually operated, so the range of use will be narrow.

3. What are the characteristics of self-tapping screws - easy to operate

Self-tapping screws combine taps and bolts, which is very practical, especially on some soft materials, which can be directly screwed in by drilling a hole. Of course, if the screw diameter is small and the wood material is soft. It can be screwed in without drilling.

4. What are the characteristics of self-tapping screws - strong self-drilling ability

Three parameters, such as self-tapping screw and screw diameter series, number of threads and screw length, determine its quality. The screw diameters on the market are divided into grades 10 and 12, and the corresponding diameters are 4.87mm and 5.43mm respectively; the number of threads is 14, 16, and 24. If you want a screw with strong self-drilling ability, it is recommended to buy it. A screw with a higher number of threads.
