The male and female Screws are mainly used in computer, circuit board and other industries. When one end is screwed into the locked object, the hexagonal column is exposed, which can fix or isolate other objects. The male and female screws are assembled on the computer host. The external thread connects the main board inside the host. The internal thread separates the main board from the sheet metal shell. The terminal line to be connected is connected with a screw from the internal thread of the sheet metal shell and the male and female copper column.
The main specifications of male and female screws are m3, M4, M5, M6, M8, m10and so on. Their hexagonal columns are 5, 6, 8, 10, 12, 15mm and so on, among which m3 series is the most suitable. In addition to copper, there are stainless steel, fast cutting steel and so on.
