Self-drilling screws, also known as Tek screws, are fasteners that can drill their own pilot holes as they are being installed. This feature eliminates the need for pre-drilling, significantly reducing assembly time and effort. Their design typically incorporates a drill point, which allows the screw to penetrate hard materials, including metal and wood, without additional tooling.

Understanding Tek Screws for Thick Steel

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.

3. Reduced Friction The phosphate coating reduces friction during installation, which makes driving the screws easier and quicker. This can lead to significant time savings during large-scale drywall projects, allowing contractors to work more efficiently and meet tight deadlines.
