16d Nails
16d nails are the glue that holds your home together. When building
stairs you will use quite a few of them. A 16d nail is three and one
quarter inches long. They come in commons, galvanized, bright and
sinkers.
If you are using them outside you will want to use the
galvanized nails. Inside you will want to use 16 sinkers but feel free
to use the galvanized because they do actually have a greater holding
power than sinkers.
