2. Corrosion Resistance Many manufacturers provide M20 bolts with coatings or treatments (like galvanization) to enhance corrosion resistance. This is vital for outdoor and industrial applications where exposure to moisture and chemicals is common.

Considerations When Using Self-Drilling Screws

3. Thermal Expansion Materials expand due to heat. When temperature variations occur, the differing rates of expansion between the anchor bolts and the material they are affixed to can create stress, leading to loosening. This is especially common in environments with extreme temperature fluctuations.

2% self-drilling screws represent a significant advancement in fastening technology, offering numerous benefits that are highly valued across various industries. By combining ease of use, versatility, and increased strength, they provide solutions that enhance efficiency and effectiveness in both professional and personal projects. As demand for reliable fasteners continues to grow, the role of self-drilling screws, especially those adhering to specific standards like the 2% classification, will undoubtedly play a pivotal role in shaping the future of construction and manufacturing practices.
