Ring shank nails offer superior holding power over smooth shank nails because the wood fills in the crevasse of the rings and also provides friction to help prevent the nail from backing out over time. A ring shank nail is often used in softer types of wood where splitting is not an issue.

3.Ring Shank Nail – Embedded Strength in the Wood
Ring shank nails, sometimes called annular ring nails, nail with rings on the shank added about 40% more holding power than those with smooth shanks. Ring shank nails may be similar to screw nails except for the flathead. The ring patterns vary according to customs’ intended applications including shallow rings, deep rings, etc.
With ring shank design, these nails provide a tight grip, additional resistance to pop-out of the wood and have proven to be the best solution to working with softwood. While other conventional nails are pulling out from lumber easily, this one is hard to remove without damaging the woods in that wood fibers settle into the spaces between rings and form a strong bond when the nail being driven into the softwood. The removal will leave a large and ragged hole if the nails are pulled out roughly. So it is extremely used for permanent construction fastening, including
Ring shank or annular nails separate the wood fibers, and then the fibers lock back into the rings which resist removal. These nails are typically used in softer woods. This type of nail is also used for drywall or deck board applications because of the pullout resistant feature of the annular rings on the nail shank. They are designed to provide a better grip with material that may otherwise be forced apart by nails. Just like using Screw Shank nails incorrectly on softwood can result in wasted material, using a Ring Shank nail on a piece of hardwood material will cause irreparable damage to the material if the nail is removed.
