According to the shape of the plane figure, the thread can be divided into triangular, rectangular, trapezoidal and zigzag threads. According to the winding direction of the helix, it can be divided into left-handed thread and right-handed thread. It is stipulated that when the thread is upright, the helix rises to the right to become a right-handed thread, and to rise to the left to become a left-handed thread. Right-handed threads are generally used in machinery manufacturing, and left-handed threads are only used when there are special requirements. According to the number of helices, it can be divided into single thread and equidistant multi-thread. For the convenience of manufacturing, the thread generally does not exceed 4 lines.
