Pan-head screws and round-head screws are often difficult to distinguish because of their similar appearances. In fact, different screw head types have different uses. Below we introduce the difference between round head screws and pan head screws, I hope it will be helpful to everyone. 　　The main differences between round head screws and pan head screws are as follows: 　　1. Differences in the definition range: Round-head screws include a larger range. As long as the screw head is round, they can be called round-head screws. Round head screws include pan head screws, large flat head screws and so on. In short, as long as the head of the screw is round, it can be called a round screw. 　　2. Differences in appearance: The most intuitive difference is the difference in appearance. Of course, this mainly refers to the head shape.

For round head screws, due to the shape of the head, the semi-circular screw head is exposed to the mounting surface after installation, often It is used for workpieces that do not require high tightening appearance. 　　5. The difference in material usage: Pan head screws and round head screws with the same specifications, round head screws are significantly larger than the pan head screws in terms of volume, weight and surface area. 　　The above is the introduction of the difference between round head screws and pan head screws.
