Self-tapping screws designed for wood are screws that can cut their own threads into the wood, eliminating the need for pre-drilling. These screws typically have a sharp point and threads that are designed to grab and hold the wood fibers. They are ideal for projects where strength and durability are required, such as furniture, decks, and fences. When selecting self-tapping screws for wood, it is important to consider the size, length, and material of the screws, as well as the type of wood being used.
