How Are Screws Made?

Screws are a very common fastener and are used in a wide range of applications. Some people may want to know their production process of them. As a professional fastener manufacturer, Xinchi Fastener Company can satisfy your curiosity and show you how are screws made.

The production of a screw usually goes through 5 steps: drawing, cold heading, thread making, heat treatment, and surface treatment.

Wire drawing is the drawing of a roll of steel wire into a wire rod of suitable thickness, hardness, and softness.

Cold heading deforms metal, a key step in screw forming. Through one mold after another, the metal morphs and gradually reveals the outline of the screw.

Thread rubbing: How are threads formed? Was it cut by a lathe? Of course not! The screw is pushed on the “washboard” and rolled over, and then the thread is on the body. With a thread, this is a real screw!

I remember a veteran compared the heat treatment of fasteners to cooking rice, or very vivid. In fact, this is a process of cooking “industrial rice”, soft or hard, depending on the need.

Finish: The fasteners have been transformed and reborn in the furnace, and now they are ready to shine. Don’t worry! The finish is the final step to make the screws look beautiful and resist the environment over time.
