Different Types of Nails and How to Use Them

Walking into the nail aisle at your local hardware store can sometimes feel overwhelming. All these little bits of sharp metal that all look almost exactly alike but aren’t, and presumably, all have different functions. Where to begin?

One characteristic of nails is that they are designed to fasten pieces of material together. Nails are a simple and basic type of fastener that has been used in construction in one form or another for upward of 3,000 years, making them one of the most time-tested items used in building. Typically, nails are used to fasten pieces of wood or timber, but can also have other uses. The wide variety in nail shape, size, and design makes them functional for specific uses. With this in mind, let’s explore the variety of types of nails to understand which types are suited for what uses.

Nail Size and Design

Nail size is determined by both length and gauge. Nail length is indicated by the letter “d,” which is a system of measurement that dates back to old England and originally represented the word “pennies.” Nails come in many lengths ranging from 2d all the way to 50d with corresponding lengths.

  • 2d – 1 inch
  • 3d – 1 1/4 inches
  • 4d – 1 1/2 inches
  • 5d – 1 3/4 inches
  • 6d – 2 inches
  • 8d – 2 1/2 inches
  • 10d – 3 inches
  • 12d – 3 1/4 inches
  • 16d – 3 1/2 inches
  • 20d – 4 inches
  • 30d – 4 1/2 inches
  • 40d – 5 inches
  • 50d – 5 1/2 inches

The nail gauge is the measurement of the nail’s diameter. The higher the gauge, the thinner the nail. Different purposes will require a different nail size and gauge. A good rule of thumb is that you should use a nail that is three times as long as the thickness of the material you are fastening.
