A wood screw is a type of fastener specifically designed for joining pieces of wood together. It features a sharp point that allows it to penetrate wood easily, and its spiral threads provide a strong grip. Wood screws come in various lengths and diameters, making them suitable for different applications in woodworking and construction. Typically made from metal, wood screws can be coated to resist corrosion. They are often used in furniture assembly, cabinetry, and other woodworking projects. The head of a wood screw can be flat, round, or oval, allowing for different types of tools, such as a screwdriver or drill, to be used for installation.
