Abstract
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 wedges are driven into the receptacle to cause its expansion in horizontal and vertical directions. This secures the members together along relatively large shear areas thereby decreasing the possibility of shear damage to the members.
