The invention relates to an expansion fastener device that secures two interlocking members together. The device includes a parallelepiped receptacle having slits along opposite ends. The receptacle is inserted through the interlocking members and double wedges are driven into the receptacle. The double wedges includes a first wedge having tapers in the vertical direction and its insertion into receptacle causes only vertical expansion of the receptacle. A second horizontal tapered wedge is received with a horizontal tapered opening formed in the first wedge to cause independent expansion of the recess in the horizontal direction.
