Another advantage of self-drilling anchor screws is their resistance to corrosion and rust. This is particularly important for outdoor or humid environments, where traditional screws may degrade over time. By choosing self-drilling anchor screws made from corrosion-resistant materials, such as stainless steel, you can ensure that your installations remain secure and reliable for years to come.

The Role of Washers

Expanding metal wall anchors are designed to hold heavy items by distributing the load across a larger area within the wall. They typically consist of a metal sleeve that expands when a screw is driven into it. This expansion action grips the surrounding material, creating a solid anchor point that can support significant weight. They are particularly useful in scenarios where traditional screws might loosen over time, such as in drywall installation or when hanging items from concrete surfaces.
