What material are screws made of?

Typically, screws and bolts are made from steel due to its strength and relatively inexpensive cost. However, screws and fasteners can also be produced from stainless steel, brass, titanium, and a wide range of other metals depending on the intended application.

What materials are used to make a screw?

Screws are generally made from low to medium carbon steel wire, though this material can be substituted for other inexpensive metals, such as brass, nickel alloys, and an aluminum alloy. The quality of the metal, however, must be high to avoid cracking and breaking in the screw.
