Understanding Nail Sizes

Hammer and nails. Just like peanut butter and jelly, it is a classic combination that has always existed. Do you Understanding Nail Sizes?

To Although hammers and nails seem simple, do you know which nails to use in each application? Nails also have right and wrong uses. Suitable nails have the strength, size, and other design features suitable for the job at hand. The wrong nails may cause weak connections and/or damage to the wood.

To The physical principle of how nail art works is simple. When nailing the wood, the shaft of the nail pushes the wood fibers away when the needle tip penetrates. The fixing force of the nail comes from the simple friction of the displaced bentwood fibers that clamp the shaft of the nail. The nails come in different sizes and shaft configurations. So that it can maximize their retention in different applications.

Nail Materials

Nails can be made from a variety of metals, including ordinary steel, stainless steel, brass, copper, or aluminum. Or, nails can be galvanized or plated with zinc or another metal. Most construction nails are steel, often with some kind of surface coating.

Many construction nails are coated with a thin layer of vinyl, which acts as a lubricant when driving the nail. Nails can also be coated with phosphate to improve their holding power. A nail that is uncoated in any way is often called a “bright” nail. 

How Nails are Size. The Spruce / Margot Cavin You’ve heard of nail sizes referred to as 10d, 16d, and so on. The number and “d” suffix are called the “Penny” system. The English penny used to be designated with a “d” representing the first letter of the Roman coin denarius. Originally, the penny number referred to the cost for 100 nails of a particular size. An 8d nail, for example, cost 8 pennies for 100.  Today, the penny system refers specifically to nail length. A 2d nail is 1 inch long, for example, while a 16d nail is 3 1/2 inches long. Each higher number in the penny system represents a 1/4-inch length increase, up to a 12d nail (3 1/4 inches long). After the 12d nail, the penny system does not have a clearly defined relationship to length.
