3. Sleeve Anchors These are similar to masonry anchors but are often used in conjunction with non-masonry materials. They have a sleeve that expands against the wall material when the screw is tightened, making them versatile for various applications.

Self-drilling screws are widely employed in multiple fields due to their versatility. In the construction industry, they are commonly used to attach metal roofing panels, siding, and steel frames. Their ability to create strong connections in metal components makes them invaluable for structural applications.

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.
