A screw mainly consists of three parts: the head, the shank, and the thread. The head is the tip of the screw, used to apply torque; common types include hexagonal, round, and flat heads. The shank connects the head and the thread, and its length and diameter vary depending on the needs. The thread is a helical protrusion used to mate with a nut or internal threaded hole to achieve a tightening function.
In addition, screws may include washers, anti-loosening devices, and other auxiliary components to enhance the tightening effect or prevent loosening. Screws are widely used in machinery, electronics, construction, and other fields. Choosing the appropriate screw type and specifications is crucial to ensuring connection strength and reliability. We currently offer molded screws suitable for various materials such as PE, PP, and PS, and can power motors up to 2000KW.
