The invention relates to an apparatus for aligning fasteners having radially symmetrical polygonal heads in a device for feeding these fasteners to a processing station. A tubular piece having axially running grooves in its interior is provided in a feed channel for the fasteners, the number of these grooves corresponding to the number of edges on the heads of the fasteners, and the diameter of the groove corners on the inlet side of the tubular piece being greater than the width across the corners of the polygonal heads, the grooves tapering from a large width to a narrow width in the transport direction in such a way that fasteners entering the tubular piece are captured with a great clearance in relation to the grooves and leave the tubular piece with narrow clearance and therefore in the aligned position.
