Like other nails, ring shank nails are not designed for optimal removal. They are used for permanent construction. The shanks make these nails even less easy to remove than conventional nails, and the removal of ring shank nails will leave a large and ragged hole behind. Although ring shank nails may look like screws, they are not designed to function like screws, and this is important to remember.
When working with softwoods, ring shank nails are extremely useful. Conventional nails tend to pull out easily under pressure from woods like pine, which is definitely not desirable. The deformed shanks keep the nails in position, even under intense pressure. Enough weight or pressure will eventually cause either the wood or the nails to fail, with ring shank nails providing around 40% more holding power than smooth shank nails.
It can be useful to keep a box of ring shank nails around for various home improvement projects. It is possible to find galvanized and treated nails which will resist corrosion, along with basic steel nails. Nails which have not been treated may be oiled for storage so that they do not rust, which explains why nails sometimes have a strange texture when they are taken out of the box.
