Ring shank nails, sometimes called annular ring nails, are nails with rings on the shank for added about 40% more holding power than those with smooth shanks. Ring shank nails may be similar to screw nails except the flat head. 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 soft wood. 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 are driven into the soft wood. 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
