<p>A harpoon nail (22) having two or more sets of teeth (40, 42) on opposite sides of fingers (36, 38) that deform while penetrating the framing members (12, 14). The teeth (66) engage with a bottom surface (78) to fasten the framing members (12, 14) together. A piercing nail (122) having sets of teeth (140, 142) on two edges (137, 138) penetrates through framing members (12, 14) and the teeth (188) engage with a bottom surface (78) to fasten the framing members (12, 14) together. A piercing nail (222) with a spring member (234) that deforms as the nail (222) penetrates through framing members (12, 14) engages with a bottom surface (78) to fasten the framing members (12, 14) together. A self-locking nail (322) having two members (324, 326) that move relative to one another when penetrating through framing members (12, 14) fastens the framing members (12, 14) together.</p> |
