The Humble Nail – A Key to Unlock the Past
When dating a piece of antique furniture, one of the most important clues to its history is often overlooked. A nail may not be a noticeable style feature, but looking at them carefully can help you authenticate the age of a primitive or antique furniture piece before you buy. Like restorers of historical buildings, you can identify the period by the technology used to create the nails and unlock the past of furniture.
Until the 18th century, nail production methods had not changed for hundreds of years. Iron ore and carbon heated together and then cooled created wrought iron, from which a nail length piece was cut and hammered on four sides to create a point. Hand-wrought nails have tapered but irregular and crooked square shafts.
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. After heating the rod in a forge, the nailor would hammer all four sides of the softened end to form a point.
The pointed nail rod was reheated and cut off. Then the nail maker would insert the hot nail into a hole in a nail header or anvil and form a head with several glancing blows of the hammer. The most common shape was the rosehead; however, broad “butterfly” heads and narrow L-heads also were crafted. L-head nails were popular for finish work, trim boards, and flooring.

Only the head and the point were forged, so these nails, which were common from the 17th to the early 19th century, can be distinguished from earlier ones by the sharp regular profile of the cut section. Machine-Cut Nails The first machined nails were flat and headless. From these were produced from rolled sections of plate iron, cut into strips of the same width as the length of the nail.
The strip was then placed under a powerful guillotine which cut off a single nail on an angle. Then the sheet was turned over and the next was cut.
Common place in the late th century through the mid th century, Date Nails were driven into railroad ties, utility poles, bridge timbers, and other wooden structures for record keeping purposes. Today, Date Nails are highly sought after artifacts by Railroadiana collectors. Following the Civil War , the railroad race was in full swing. In one such race, the Union Pacific and Central Pacific would compete for government favor; with the line that built the most miles being rewarded with cash and land.
In order to keep pace with this expansion, the timber needed to produce crossties was in high demand. Left untreated, wooden crossties had a life expectancy of only five to seven years. Based on the frenetic pace of laying new track and the subsequent demand of timber supplies, rail companies hatched the idea of treating the ties to increase their life expectancy.
Not knowing which type of wood and treatment methods would be the most effective and economical, railroads began to experiment with varying treatments in the mid to lates. To monitor the results of differing test sections of crossties, railroads settled on the idea of using Date Nails for record keeping purposes. The oldest known Date Nail used in the U.
Most Date Nails were made of steel, though copper, aluminum, iron, and even brass were also used. Nails were driven into ties at either the treatment facility or at the time they were installed into the track. Nail heads were produced in a variety of shapes — round, square, diamond, pentagon, and other rarer shapes. Some railroads used shapes to indicate if a tie had been treated or not, or if the tie was re-used.
