2. Slab Thickness The thickness of the concrete slab affects the length of the shear studs. A thicker slab will necessitate longer studs to ensure that they are adequately embedded within the concrete.

1. Metal Roofing These screws are ideal for securing metal sheets, as they can penetrate the material easily and create a watertight seal, ensuring long-lasting protection against leaks.

3. Plastic Expansion Anchors These are lightweight anchors often used for lighter objects in drywall. They consist of a plastic body that expands when a screw is inserted, providing a reliable grip for small shelves, frames, or lightweight decorations.

The hallmark of self-drilling screws is their ability to create their own pilot holes, negating the need for pre-drilling, which can save significant time and effort during installation. The 13mm self-drilling screw is typically constructed from high-strength steel, ensuring durability and reliability. These screws often feature a sharp, drill-point tip which enables them to penetrate various materials quickly and efficiently. Coupled with a robust thread design, they provide excellent holding power, making them ideal for fastening metal, wood, and other materials.

4. Corrosion Resistance The white finish often includes protective coatings that resistant to rust and corrosion, which is critical in outdoor or high-humidity applications. This quality ensures the longevity of the fastening solution and reduces the frequency of replacements.
