Wire nails are formed from wire. Usually, coils of wire are drawn through a series of dies to reach a specific diameter, then cut into short rods that are then formed into nails. The nail tip is usually cut by a blade; the head is formed by reshaping the other end of the rod under high pressure.
In woodworking and construction, a nail is a small object made of metal (or wood, called a treenail or ''trunnel'') which is used as a fastener, as a peg to hang something, or sometimes as a decoration.
