Definition & Meaning of "corrugated nail"

What is a "corrugated nail"?

A corrugated nail is a type of nail that features a wide, wavy shaft, designed to provide a strong, secure hold when fastening materials together. The wavy, or corrugated, design increases the surface area of the nail, allowing it to grip the wood or material more effectively. Corrugated nails are commonly used in woodworking, particularly for attaching thin sheets of wood or plywood, as the unique design helps prevent the nails from pulling out. These nails are often used in framing, paneling, or constructing small furniture pieces where a firm grip is needed.
