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.
Why is using a screw better than using a nail?
When deciding between nails and screws, keep in mind that nails are less brittle, so they provide greater shear strength. … Screws, on the other hand, may not be as forgiving, but their threaded shafts hold better in wood and draw boards together much more tightly and they have greater tensile strength.
When should you use screws instead of nails?

Screws are widely used in threaded fasteners to hold objects together, and in devices such as screw tops for containers, vises, screw jacks and screw presses.
What are the disadvantages of using screws?
Screws can rip right through certain materials, making them a poor fastener choice for weak, thin woods. Door skin (1/8-inch plywood) and similar materials may allow screw heads to sink or rip right through. Very soft woods such as balsa will also sink or dent under the pressure of a screw head being driven in.
