Abstract: An automatic fastener supplier includes a frame having a receiving section for receiving fasteners. A track is removably and partially mounted in the receiving section. The track includes a gap defined therein for receiving shanks of the fasteners and an upper open edge for retaining heads of the fasteners. A fastener feeding device is mounted in the receiving section and is vertically movable for feeding fasteners in the receiving section onto the track. A main driving device is provided for driving the fastener feeding device to move vertically. A stop is mounted to the front end of the track for preventing further forward movement of the fastener. A track supporting device has a supporting member for supporting the track yet allowing insertion and removal of the track. A position deciding device is mounted to the supporting member for adjusting a longitudinal position of the track.
