Finishing nails are slender, typically about 1 to 2.5 inches long, and are designed for subtlety in woodworking. Unlike standard nails, finishing nails have smaller heads that allow the nail to be driven below the surface of the wood. Once the nail is countersunk, the surface can be filled with wood putty or painted over, resulting in a clean and professional finish. This feature is particularly important for projects where aesthetics are crucial, such as in crown molding, trim work, and fine cabinetry.
