ABSTRACT:
Screw fasteners are used to connect multiple trusses in side-by-side relationship. The screw fasteners join truss wood members which are in edge to edge relationship with the screws being driven through the edge of each wood member. The screws may be knurled screws as described in U.S. Pat. No. 6,109,850; lag screws, or standard screws. The connection may also join wood board members in edge-to-edge relationship when bending of the wood members is limited by a restraining structure.
