    摘要: A fastener for use particularly to temporarily secure wood strip members to a concrete substrate includes an upper cylindrical head overlying a first cylindrical shank, with a truncated conical further head coaxially aligned with the cylindrical head, with a second shank positioned between the further head and an elliptical, deformable anchor portion including a third shank underlying the anchor portion. The anchor portion is deformable to enhance securement of the fastener within the concrete substrate, and wherein further the cylindrical head and the further head define a gap therebetween to enable removal of the fastener by application of a tool to the first shank.
