A calibrated gusset plate for joining a pair of abutting wooden members in the construction of roof trusses, floor or ceiling joists and the like. In a preferred embodiment the calibrated gusset plate is characterized by a rectangular sheet metal gusset plate stock having multiple prongs which are struck from the gusset plate stock and projected to one side thereof in a series of longitudinally-extending rows. A calibrating mark such as a notch is formed in the mid-point of each longitudinal edge and each transverse edge of the gusset plate for alignment with the abutting surfaces of a pair of wooden truss members which are to be joined by the calibrated gusset plate. In another embodiment, a calibrating bead projects from the gusset plate on the side of the prongs at the mid-point of each longitudinal edge and at the mid-point of each transverse edge of the gusset plate. In still another embodiment, a scribe is formed in the gusset plate, at the mid-point of each longitudinal and transverse edge of the gusset plate. An in yet another embodiment, a calibrating aperture or opening is provided in the gusset plate, at the mid-point of each longitudinal and transverse edge thereof.
