ABSTRACT:
A hanger device for connecting a first wood member, such as a wood joist, to a second wood member, such as a roof or floor truss of a building structure, such that the first wood member is oriented substantially perpendicualar to the second wood member. The device is comprised of a relatively flat central member having first and second opposite ends and first and second opposite sides; a relatively flat base member extending perpendicularly outward from the central member adjacent to the first end thereof; a relatively flat flange member extending perpendicularly outward from the central member in an opposite direction from which the base member extends; and first and second walls protruding from the central member and base member in substantially the same direction as the base member. The first and second walls cooperate with the base member and central member to define a recessed region for receiving a portion of the first wood member. Respective inwardly facing surfaces of the first and second walls each have a plurality of projections extending into the recessed region for being embedded into the first wood member to attach the first wood member to the hanger device. The projections are preferably formed by extruding selected portions of the first and second walls into the recessed region to define respective openings in the walls adjacent to the corresponding projections. The projections are oriented diagonally with respect to a major axis of the corresponding wall to enhance the gripping action of the hanger device.
