The present invention relates to a device and a method associated with the device. With respect to the device, it is a structural connector for fastening structural components in insulated concrete formwork (ICF). The structural connector consists of a double threaded cylinder bolt assembly that aligns through openings in the ICF wall. One end of the cylinder bolt assembly embeds into the cavity of the ICF wall where openings in the cylinder bolt assembly receive concrete and reinforcement bars. The other end of the cylinder bolt assembly is threaded to receive a double threaded washer head bolt. The cylinder bolt assembly is used to mount ledger boards, floor joist hangers and roof truss connectors to the ICF wall, locking them together acting as one unit in withstanding bending and uplift loads imposed by large forces such as floor and roof truss systems.
