Abstract: The fastening device is for securely joining opposing surfaces of two structural members. The fastening device provides for a flush joining of opposing surfaces of two structural members to maximize strength and appearance characteristics. The fastening device is comprised of an elongated, rigid member having a head portion at one end, and means to adjustably secure it to a structural member at its opposite end. A rigid plate member, for securement in a position aligned with a recessed or apertured portion of a second structural member, is provided to communicate with the elongated, rigid member. The rigid plate member has an aperture of a predetermined configuration consisting of an enlarged apertured portion and an elongated apertured portion having a lesser width, which communicates with the enlarged apertured portion.
