What does m mean in screw?

The m in screw refers to the diameter of the screw. Screws are generally classified according to m, such as m3, m4, m5, etc. The number indicates the diameter of the screw in millimeters. The larger the diameter of the screw, the stronger its load-bearing capacity, but it is also necessary to consider the occasion of use and choose screws of different diameters to ensure safety.

In addition to the diameter, screws have other indicators, such as pitch, length, head shape, etc. Among them, the pitch refers to the distance between each circle of thread, which can be divided into standard pitch and fine pitch, and has different uses. The length refers to the full length of the screw, and the head shape is divided into flat head, round head, semi-circular head, etc., which are generally selected according to needs.

If it is for home decoration or daily use, you can choose screws of general specifications and suitable prices, but if it is for construction or machinery industry, you need to consider factors such as material, diameter, pitch and strength, and choose the right screw to ensure operation safety and quality.
