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.
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.

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.)
