Machine screw suppliers introduce you to the screw thread
The difference between mechanical screws and other screws can be based on whether they can be used with a nut. machine screw suppliers are supplied with nuts.
Compared to the screws of other teeth, there are self-tapping screws. Self-tapping screws are unneeded nuts for assembly. As for the standard thread and the fine thread, the thread distance is different. It is the nut of the machine screw. Non-self-tapping screws are machine thread screws, that is, the workpiece to be fastened by the screw must be tapped in the screw hole with a tap to match the thread.
The machine screw suppliers also want to tell you that according to the thread type, it is divided into ordinary thread, pipe thread, trapezoidal thread, rectangular thread, and zigzag thread. In addition to the pipe thread, the metric thread is used in China. Another type of mechanical thread is called a rectangular thread (the thread shape is square and the thread angle is 0 degrees). Trapezoidal thread (the isometric shape of the isosceles trapezoid, the angle of the thread is 30 degrees), serrated thread (the thread type is not equal to the trapezoidal shape, the flank angle of the working surface is 3 degrees, and the flank angle of the non-working surface is 30 degrees).
After the introduction of the machine screw suppliers, do you have a certain understanding of the screw thread?
