A hammer is a tool designed to drive nails into softer materials like wood or a wall. You can drive in a screw with the help of a hammer as well, but it is not recommended as it can damage the screw as well as the surface you are driving the screw in.

If you are dealing with large sized nails for projects like framing walls and roofs, securing plywood sheathing or installing floors, you need a hammerhead of a large size. In most of the cases, 16 OZ. hammerhead can sufficiently drive in the nails from ½ inch tacks to 16 penny nails.

Finishing nails have a small nail head and can be driven slightly below the surface of the wood where it can be concealed with wood putty. In such an instance, hammers can be used for nailing up interior moldings, installing exterior house trim like rake boards, fascia, frieze or corner boards, or fixing stiles and rails to the cabinets.

Screw Drivers

A screwdriver is a tool used for screwing or unscrewing the screws into different surfaces. Ideally, a screwdriver is used in projects like hanging drywall, attaching ledger boards, installing cabinets, fastening wood decking or fabricating cabinets, wooden toys, bookcases, and other woodworking projects.
