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.

The rise of self-drilling screws has also spurred innovation in the construction and engineering industry, leading to the development of new building techniques and designs. With the ability to quickly and securely fasten materials, builders and engineers are empowered to explore more ambitious projects and push the boundaries of traditional construction methods. This has led to the creation of more resilient and sustainable structures that can withstand the test of time.
