A connector plates for joining together wooden members is formed by striking out longitudinally aligned rows of pairs of teeth from a thin metal plate leaving a single elongate slot in the plate between the two teeth of each pair. Each of the pairs of teeth in each row is longitudinally staggered relative to the pairs of teeth in adjacent rows a distance sufficient to position each tooth of each pair slightly longitudinally offset from a tooth of a pair of teeth in a laterally adjacent row. Each tooth of each pair of teeth includes an elongate shank section rising upwardly from the metal plate, an asymmetrically shaped tip section extending upwardly from the shank section, and a laterally offset point at the upper end of the tip section. The tip sections of each tooth are configured so that the teeth of adjacent rows which are slightly longitudinally offset relative to each other have their points alternating laterally offset toward and then away from each other along the length of the connector plate. Furthermore, the base or lower portion of the shank section of each tooth is slightly twisted about an axis extending longitudinally of the height of the tooth while the upper portion of the shank of each tooth remains generally transversely symmetrical about such longitudinal axis so that the side edges of the shank upper portion actually extends laterally outwardly of the corresponding edges of the shank base portion.
