Abstract: A fastener magazine of, e.g., an electric screwdriver into which connected fasteners of various girths can be loaded to improve the versatility. A fastener magazine (5) of a fastening machine has therein a press plate (9) of spring-pressing type opposed to feed pawl (8) of a fastener feed mechanism. The pressing plate (9) is disposed at a height at which the connecting belt (B) of the connected screws (S) is placed and presses the shafts of the connected screws (S) against the wall face of the feed pawl (8) side. The connecting belt (B) is placed on the top face of the pressing plate (9) and supported. The fastener passage is so broad that even thick fasteners can be loaded, and therefore screws of various girths can be held at predetermined heights. Since the connected screws (S) are pressed against the wall face of the feed pawl (8) side, the engagement between the feed pawl (8) and the connected screws (S) is stable, and resultantly the reliability of screw feed is improved.
