When selecting screws for wood projects, it's crucial to choose those specifically designed for woodworking applications. Wood screws are available in various types; however, two common options are flathead (slotted) and Phillips-head screws. Flathead screws have a single slot across their head that requires a flathead screwdriver, while Phillips-head screws have a cross-shaped groove compatible with Phillips screwdrivers. Both types work well in different scenarios, but Phillips-head screws typically offer better torque transfer and don't require alignment with slots like flathead screws do. Ultimately, it's important to consider factors such as length, thread type, and material compatibility when determining which type of screw is best for your specific woodworking project.
