Zinc Countersunk Torx Concrete Screw is a specialized fastener designed for use in concrete and masonry applications. The screw is made of zinc-coated steel, which provides corrosion resistance. Countersunk head design allows the screw to sit flush with the surface when fully tightened. The "Torx" drive (also known as a star drive) offers better torque transfer and reduces cam-out compared to traditional Phillips or slotted drives.
