What are common materials used to make bolts?

Bolts are commonly made from materials that offer strength, durability, and resistance to corrosion. Steel, stainless steel, and brass are popular choices due to their mechanical properties.

Steel is widely used because of its high tensile strength and hardness, making it suitable for a variety of applications. It can be heat-treated or alloyed to enhance its properties even further.

Stainless steel offers corrosion resistance due to the presence of chromium, which forms a protective layer on the surface. This property makes it particularly useful in environments that may expose bolts to moisture or corrosive substances.

Brass, an alloy of copper and zinc, is also utilized for its good strength and resistance to corrosion, especially in applications involving marine environments or electrical components.

While other options may include materials like iron, titanium, or plastics, they do not match the combination of strength, versatility, and resistance that steel, stainless steel, and brass provide in the context of the most common materials used for manufacturing bolts.
