Answer:
While nails have more flexibility, screws have more tensile strength. Tensile strength refers to a material's ability to resist breaking under pressure. This makes screws better for projects when joined pieces are under tension or bearing weight, like porch railings or kitchen cabinetry.

Step-by-step explanation:
A screw is actually a kind of inclined plane wrapped around a cylinder. A screw has two ends : a narrow end and a flat end. The narrow end of the screw is called the tip and the flat end is its head. Screws are more useful than nails because they hold things together with a strong grip due to more friction.
Bigger screws are used in screw jacks to lift cars and other heavy objects.
