Another crucial aspect of bolt structure is the surface treatment of bolts, which can significantly improve their performance. Surface treatments such as galvanization, coating, or anodizing can enhance a bolt's resistance to corrosion and wear, extending its service life. For instance, galvanized bolts are coated with zinc to prevent rusting, making them suitable for outdoor applications. Similarly, anodized bolts, commonly used in aluminum alloys, have a protective oxide layer that not only enhances corrosion resistance but also improves aesthetic appeal.
