What Is A Nail

Nails are pointed heads of hard metal (usually steel) used to hold things such as wood. Hammers drive nails into objects, and recently there are electric nail guns, gas nail guns. The reason why the nail can stabilize the object is that it hangs on it by its own deformation and relies on friction. Nails are one of the most common things in renovations. Iron-cast nails are also called iron nails, and steel-cast nails are also called steel nails.
