Boat Nails are commonly used in wood boat construction and repair. They will not rust or corrode in marine use. The ring grooves shape the wood fibers into tiny wedges. The wood fibers then spring back, filling the grooves between the rings, thus "locking" the nail. These nails offer holding power comparable to wood screws.
