Finishing nails are small, slender nails used in woodworking and construction to attach trim, moldings, and other decorative elements. They typically have a small head that can be easily concealed, allowing for a clean and polished appearance in finished projects. These nails are usually made of steel and come in various lengths, ranging from 1 inch to 2.5 inches. Finishing nails are often driven into the wood using a hammer or a nail gun, and their design helps prevent splitting of the wood while providing a strong hold for lightweight applications.
