    (57) The quality control device, particularly for screws, bolts and the like, has an electromagnetic vibrating feeder (1) for feeding screws and/or bolts which feeds screws and/or bolts to a conveyance and checking station (2). The conveyance and checking station (2) includes a section (3) for checking the head of the screws and/or bolts and a section (4) for checking the stem of the screws and/or bolts. The head checking section (3) removes the screws and/or bolts from the electromagnetic vibrating feeder (1) and conveys them through an analysis device toward the stem checking section (4). The stem checking section (4) is provided with a reading device (29,30), and a device (5) for selectively discharging the screws and/or bolts is located downstream of the stem checking section (4).
