Because they said so
In earlier times, the size of a nail was set by the cost of 100 nails in pennies. The names persisted although the prices fluctuated.
That would depend on the type (common, roofing, concrete) and their size as measured like a two penny (2d) nail and so on. For example 60d common nails are 10 to the pound and 2d roofing nails are 225 to the pound.
A pound of 10 penny (10d) galvanized nails typically contains about 30 to 35 nails, depending on the specific size and manufacturer. This variation occurs because the weight of individual nails can slightly differ based on coating and production processes. If you need a precise count, it's best to refer to the packaging or manufacturer's specifications.
In value, a penny is smaller. In size, a dime is smaller.
There are 225 2d roofing nails in a pound. If you need something longer like 1.75 inches that would be a five penny (5d) and there are only 145 in a pound.
Construction nails are called "penny nails" because the term originates from the historical practice of pricing nails by the penny. The "penny" referred to the cost of a hundred nails in the past, with larger nails being denoted by a higher number. For example, a "2d" nail (two-penny) would have cost two pennies for a hundred nails. This system of naming has since continued, causing the term "penny" to be associated with the size of the nails.
The term "10 penny nail" comes from the old English word "penny," which referred to the price of nails in the 15th century. Specifically, a "10 penny" nail was one that cost ten pennies for a certain quantity, typically a hundred nails. The "penny" measurement reflects the size and length of the nail, with larger numbers indicating longer nails. Today, a 10 penny nail is approximately 3 inches long.
16 penny nails, often referred to as 16d nails, are a type of common framing nail used in construction and carpentry. The "16" signifies the penny size, which dates back to the historical practice of pricing nails by the penny; a 16d nail is approximately 3.5 inches long. They are typically used for framing, decking, and other structural applications due to their strength and durability. These nails can be made of various materials, including steel, and may come with different coatings for added corrosion resistance.
It is a measure of the size of the nail, the term dating back to the 1500s. The penny nail size was originally the price in pennies of 100 nails of that size.
The term "penny" in nail sizing is derived from the British system where nails were sold by the pennyweight. The number associated with each size referred to how many pennies it took to buy 100 nails of that size. For example, a 10d nail cost 10 pennies for 100 nails. This system has been retained in modern nail sizing for historical reasons.
Ten penny nails, often referred to as "10d nails," are a type of fastener used in construction and woodworking. The "penny" designation comes from an old British system where the number indicates the length of the nail; a 10 penny nail is typically 3 inches long. They are commonly used for framing, sheathing, and other structural applications due to their strength and length. In terms of gauge, ten penny nails usually have a diameter of about 0.135 inches.
The term "penny" for nails comes from the historical practice of pricing nails based on their weight in pennies. For example, a "penny nail" referred to a nail that cost one penny per pound. The abbreviation "d" stands for the Latin word "denarius," which was a coin used in ancient Rome, further linking the measurement of nails to monetary value. Over time, the penny system and the Latin abbreviation became standard in the industry.
A 16 penny nail is typically made of steel, which provides strength and durability for various construction projects. The term "16 penny" refers to the nail's size and weight, with longer nails typically having a higher penny size.

"Penny turtle" is a term used to describe freshwater turtles that are found in our lakes and ponds. They are referred to as such because they are very small as juveniles, about the size of a penny, and grow up to the size of a dinner plate.
Many different size nails have 'ribs' on them.They are to make it harder for the nail to be pulled out.A 'spiral' ( ardox ) nail is even harder to pull out.
Yes. d is the symbol for a British pence, which is like an American penny. I'll answer the question you didn't ask: why do they use pennies as the unit of measure of nails? Many years ago nails were sold loose, and they were counted out rather than being weighed. The number of pence, or cents, 100 nails in that size would cost you many, many years ago determined the "penny" size. If 100 3-1/2" nails cost 16 pence, they were considered "16 penny" nails. (This also meant there weren't standard nail sizes--if Tom's Hardware charges 16d for 100 3" nails, and Dick's wants 16d for four inch nails. you'd have to go to Tom's for all your nail needs.)
