The choice of materials in bolt construction is paramount as it directly influences the strength and durability of the component. Common materials used for bolts include high-carbon steel, stainless steel, and alloy steel, each offering different mechanical properties to suit specific environments. For example, stainless steel bolts exhibit excellent corrosion resistance, making them ideal for applications in maritime environments and industries that handle corrosive substances. In contrast, high-carbon steel bolts offer enhanced tensile strength, which can be critical for high-stress applications.
