Which type of screws are specifically designed to fasten wood?

Wood screws are specifically designed to fasten wood due to their unique features that enhance grip and hold in wooden materials. They typically have a tapered body and are equipped with sharp, coarse threads that allow them to bite into the wood and provide a secure fastening. The pointed tip facilitates easier insertion and minimal splitting of the wood, making them effective for various woodworking applications. These screws are often used in furniture assembly, cabinetry, and general construction where wood is involved, ensuring strong connections that can withstand the mechanical stresses typically encountered in wood joints.

Other types of screws, although useful in various applications, do not share these characteristics tailored for wood fastening. Machine screws, for instance, are designed for fastening metal parts together and are not suitable for wood due to their finer threads. Lag screws, while they can also fasten wood, are specifically designed for heavy-duty applications and have a larger diameter, making them less versatile for general wood fastening. Cap screws are intended for mechanical applications and are meant to be used with nuts, not for direct wood fastening.
