We use nails in construction and carpentry to fasten one or more objects to each other. They are usually made of steel but can also be made of stainless steel, iron, copper, aluminium or bronze. In this category, you will find different types of nails depending on the material you want to drive them into and the degree of holding power you require. They include but are not limited to steel and wire nails, U nails, roofing nails and wood nails. Some of the nails in this section are specially hardened so that they can be driven into masonry or concrete, usually in the act of attaching wooden items to these materials.
