An automatic fastening device includes a driving mechanism for driving a double-headed fastener and a magazine for receiving and delivering the double-headed fastener to the driving mechanism. The magazine includes a first channel that receives a first head of the fastener and a second channel that receives a second head of the same fastener. The first and second channels guide the fastener along the magazine and toward an actuation component of the driving mechanism for driving the fastener into an object. A plurality of double-headed fasteners are inserted into the magazine, guided by the magazine to the driving mechanism, and driven one at a time into an object such that the first head of the fasteners extends from the object for easy removal of the fasteners.
