Nails provide one of the best clues to help determine the age of historic buildings, especially those constructed during the nineteenth century, when nail-making technology advanced rapidly. Until the last decade of the s and the early s, hand-wrought nails typically fastened the sheathing and roof boards on building frames. These nails were made one by one by a blacksmith or nailor from square iron rod.
Imagine the limited aspirations of the first pre-bronze age constructor to join two pieces of wood with a sharp implement. History does not record who it was, but the incredible results of that inspirational moment are all around us – in the houses we live in, the bridges we cross, the furniture we sit on. Nails have been around for a long time.
As soon as man discovered that heating iron ore could form metal, the ideas for shaping it quickly followed. In the UK, early evidence of large scale nail making comes from Roman times years ago. Any sizeable Roman fortress would have its ‘ fabrica ‘ or workshop where the blacksmiths would fashion the metal items needed by the army. They left behind 7 tons of nails at the fortress of Inchtuthil in Perthshire.
For nail making, iron ore was heated with carbon to form a dense spongy mass of metal which was then fashioned into the shape of square rods and left to cool. The metal produced was wrought iron. After re-heating the rod in a forge, the blacksmith would cut off a nail length and hammer all four sides of the softened end to form a point. Then the nail maker would insert the hot nail into a hole in a nail header or anvil and with four glancing blows of the hammer would form the rosehead a shallow pyramid shape.
This shape of nail had the benefit of four sharp edges on the shank which cut deep into timber and the tapered shank provided friction down its full length.

Briefly, a date nail is a nail with the date stamped in its head. For example, a nail with a “41” is from Date nails were driven into railroad ties, bridge timbers, utility poles, mine props, and other wooden structures for record keeping purposes.

Looking at antique furniture, we often seek clues for authenticity and age. There are many factors that show true historic construction, but one clue that is often overlooked is the type of nail used to hold the piece together. Nails in antique furniture are often barely noticeable, but they are another key to unlock the history of wooden pieces. The quest for the ideal nail has taken centuries of development.
The ancient Egyptians and Romans used organic glue for wood furniture, especially with decorative veneer techniques, but like much advanced technology, glue for wood became a lost art after the collapse of Rome in until the Renaissance, around , when glue and veneer techniques reappeared. During the Middle Ages, furniture was held together with pegs, dovetails, mortise and tenon joints and a few nails.

In this second post on this subject, we will address the other nail evidence that we have discovered and analyze what it might mean.

But it is apparent that the price of nails was constant, or near constant, for a long period of time, and thus, led to standard sizes as a result. For quite some time, nails have been sold by the pound–usually 1 lb. Nails are also sold by keg weight.

The parts of the nail are the head, shank or shaft, point, and the gripper marks — slight grooves incised into the shank near the head of most but not all varieties of nails. The nail functions by displacing wood fibers when it is pounded into the workpiece, and the pressure exerted against the shaft by the displaced wood provides the holding power.
Nails are sometimes referred to by their length in inches, but more often the traditional terminology of the penny is used. Dating from the days when nails cost a lot more than they do today, the term penny identifies the size of a nail. The pricing structure has long since been abandoned today, nails are sold by the pound , but the nomenclature of the penny survives.
Wire nails are indeed the rule today, but not all wire nails are the same. They vary in size and in other ways as well. Various nails are manufactured for specific purposes, with differently proportioned and shaped heads and shafts. Nails are made of brass, aluminum, and copper, though most often of steel. The steel may be plain or galvanized, the latter being the right choice for damp applications where a rust-resistant nail is required.

Historical archaeologists need to avoid the simplistic use of invention dates and patent dates and focus instead on the mass-production dates. There can be a significant amount of time between an invention and its first production, and even greater time until production figures are significantly high enough to affect the archaeological record.
Usually wire nails are ascribed an s beginning date, but that date is both too early and too late. While some wire nails were produced in , no significant quantities were produced in the United States until the mids. Thus, we need to extend the manufacturing date back some 30 years with the caveat that the effective manufacturing date range begins in the s. By examining production figures for wire nails, a model is generated for dating sites built of machine cut nails.
