countersunk self drilling metal screws

In industrial settings, 16mm self-drilling screws are commonly used in sheet metal fabrication, automotive assembly, and construction projects. They are ideal for attaching metal frames, roofing, cladding, and even for joining thick wooden structures. Their large size makes them suitable for applications where a stronger hold is necessary, such as in machinery, furniture manufacturing, or even in certain aspects of civil engineering.

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.
