Nails date back at least to Ancient Egypt bronze nails found in Egypt have been dated 3400 BC. The Bible provides a number of references to nails, including the story in Judges of the woman who drives a nail into the temple  of a Canaanite commander while he is asleep, the provision of iron for nails by King David for Solomon's Temple, and the crucifixion of Christ. The Romans made extensive use of nails, evidenced for example by the seven tons of nails left behind by the Roman army at the fortress of Inchtuthil in Perthshire in the United Kingdom. The term “penny”, as it refers to nails, probably originated in medieval England to describe the price of 100 nails. Nails themselves were sufficiently valuable and standardized to be used as an informal medium of exchange. The letter “d”, which stands for penny, is derived from the Latin name of the Roman coin, the denarius. Until around 1800, nails were made by hand, and were provided by an artisan known as a nailer or nailor. There were workmen calledslitters who cut up iron bars to a suitable size for nailers to work on. From the late 16th century, manual slitters disappeared with the rise of the slitting mill, which cut bars of iron into rods with an even cross-section, saving much manual effort. At the time of the American Revolution, England was the largest manufacturer of nails in the world. Nails were expensive and difficult to obtain in the American colonies, so that abandoned houses were sometimes deliberately burned down to allow recovery of used nails from the ashes. Families often had small nail manufacturing setups in their homes; during bad weather and at night, the entire family might work at making nails for their own use and for barter. Thomas Jefferson wrote in a letter, “In our private pursuits it is a great advantage that every honest employment is deemed honorable. I am myself a nail maker.” The growth of the trade in the American colonies was theoretically held back by the prohibition of new slitting mills in America by the Iron Act, though there is no evidence that the Act was actually enforced.
The production of wrought iron nails continued well into the 19th century, but ultimately was reduced to nails for purposes for which the softer cut nails were unsuitable, including horseshoe nails. From the very beginning, nails were handmade; the nail-making process was slow; and nails were relatively few and expensive. This naturally produced a desire to create machines to speed up and automate the nail-making process. The slitting mill, introduced to England in 1590, had simplified the production of nail rods, but the real first efforts to mechanise the nail-making process itself occurred between 1790 and 1820, initially in the United States and England, when various machines were invented to automate and speed up the process of making nails from bars of wrought iron. These nails were known as cut nails or square nails because of their roughlyrectangular cross section. Cut nails were one of the important factors in the increase in balloon framing beginning in the 1830s and thus the decline of timber framing with wooden joints. Though still used for historical renovations, and for heavy-duty applications, such as attaching boards to masonry walls, cut nails are much less common today than wire nails.
In woodworking and construction, a nail is a pin-shaped object of metal (or wood, called atreenail or "trunnel") which is used as a fastener, as a peg to hang something, or sometimes as a decoration. Generally nails have a sharp point on one end and a flattened head on the other, but headless nails are available. Nails are made in a great variety of forms for specialized purposes. The most common is a wire nail. Other types of nails include pins, tacks, brads, and spikes. Nails are typically driven into the workpiece by a hammer, a pneumatic nail gun, or a smallexplosive charge or primer. A nail holds materials together by friction in the axial direction and shear strength laterally. The point of the nail is also sometimes bent over or clinchedafter driving to prevent pulling out. To make a wrought-iron nail, iron ore was heated with carbon (to create wrought iron) and shaped into square rods. To make a nail, a blacksmith would heat the rod in a forge and taper the end of the bar while keeping the cross section square. Next, the smith would cut off the taper, and insert it into a nail heading tool with a square hole. The top of the taper would be hammered downward (upset) to create a head.
