Abstract:
1. A system for retrofitting stucco sheathing to improve resistance to seismic and other loading forces imposed on the sheathing comprising: a wood frame structure having stucco sheathing applied thereto: a fastener with a body portion having a predetermined axial length, a hexagonal head at one axial end of the body portion for being seated in a countersunk hole in the stucco sheathing; a screw threaded portion at an opposite axial end of the body and; an unthreaded shank portion extending between the hexagonal head and the threaded portion wherein the axial length of the unthreaded shank portion extends entirely through the stucco sheathing and between at least three-eighths (⅜″) inches and one-half inch (½″) into the wood frame structure whereby lateral forces imposed on the stucco sheathing are transferred from the sheathing to the wood frame structure and wherein the axial length of the unthreaded shank portion is approximately one and one-eighth inches (1⅛″) in length and the entire axial length of the fastener is approximately two and one-quarter inches (2¼″) in length and; wherein the fastener is comprised of a metal material that has been normalized to increase the ductility of the fastener and is capable of being screwed through the stucco sheathing and into the wood frame structure.
