Abstract
A harpoon nail having two or more sets of teeth on opposite sides of fingers that deform while penetrating the framing members. The teeth engage with a bottom surface to fasten the framing members together. A piercing nail having sets of teeth on two edges penetrates through framing members and the teeth engage with a bottom surface to fasten the framing members together. A piercing nail with a spring member that deforms as the nail penetrates through framing members engages with a bottom surface to fasten the framing members together. A self-locking nail having two members that move relative to one another when penetrating through framing members fastens the framing members together.
