A nail differs from a screw in the shank, the former is smooth and the latter has threads.

When you have something that has sideways pressure where the material tends to move left or right, the nail should be the first choice, if the material may separate from the top or bottom, a screw is better. Most construction nail materials are steel, nails can also be made out of stainless steel, brass, copper, and aluminum.

What is the penny size of a nail? There is a special classification of nail sizes that originated in England – Penny system, the nail size was originally named after the price of 100 nails of a given size. The “d” is the symbol for the penny. For example, 16d stands for 16 penny nail. Now, the term corresponds to the measurement of nails from the head to the tip, which is the nail length, specified by a digit and the letter “D”, which means “penny size”. So, a 2d nail is 1 inch long. More common nail sizes: a 4d nail measures 1.5 inches, a 6d nail is 2 inches long, an 8d nail is 2.5 inches long, a 12d nail is 3.25 inches long, and 16d nails are 3.5 inches long. Every increase or decrease in number means the length change in 1/4 inch.

What is a nail gauge? The nail gauge sizes indicate the thickness or diameter of a nail. The higher the gauge number, the thinner the nail is. For example, the 14 gauge nail is thicker than 15 gauge. It also measures how strong the nail is. The smaller the gauge size, the stronger the nail.

16d sinker nails  = 3-1/4″ x 0.148″ diameter, the physical sizes are close to that of 16d common nails, but the top of the sinker nails has a pattern or coating, which provides a nonslip surface for the hammer surface to help drive the nails
