Definition & Meaning of "concrete nail"

What is a "concrete nail"?

A concrete nail is a strong, thick nail designed for driving into hard materials like concrete, brick, or masonry. It is usually made of hardened steel to resist bending and breaking when hammered into these tough surfaces. The nail often has a flat head and a pointed tip to ensure it can penetrate the material effectively. Concrete nails are commonly used in construction to attach wood or other materials to concrete or brick, providing a secure and durable hold in demanding applications.
