Wood screws are used for basic wood construction and woodwork projects to attach wood to wood. The coarse threads, smooth shank, and tapered head make wood screws an ideal choice for woodwork. Unless the screw itself is self-tapping, meaning it can be driven into the wood directly, then the screw will require a pilot hole, or previously drilled hole, before you insert it into the wood. Wood screws have different types of thread depending on the kind of wood. Typically, wood screws that have fewer threads per inch are best for fastening soft woods such as pine, whereas fine thread screws are best used for connecting hardwoods such as oak.
Wood screws can have many different kinds of heads, but typically have either a round head or a flat head. A round head will sit slightly above the wood on the finished product whereas the flat head will be more flush with the finished piece. Wood screws are available in interior or exterior styles with the appropriate finishes.
