The main advantage of using screws over nails in carpentry is that screws provide better holding power. This is primarily due to their design; screws have threads that grip the material they are driven into, creating a stronger connection. The threaded shaft allows the screw to bite into the wood, which minimizes the risk of loosening over time compared to nails, which rely on friction and their smooth shaft to hold.

Additionally, screws offer greater pull-out resistance, especially in applications where lateral forces or tension might be applied, making them ideal for securing joint connections that may experience movement. This characteristic enhances the durability and longevity of the structure being built, as screws maintain their grip under various conditions better than nails. This is particularly important in applications requiring higher structural integrity and stability, such as in frame construction, cabinetry, or when attaching hinges.
