A method and apparatus are described for conveying and supplying a part, such as a projection nut, to a predetermined point in space. The apparatus comprises a telescopic supply rod including an outer and inner shaft, two magnets being associated with a proximal end of one of the two shafts. The supply rod first extends in its entirety towards the predetermined point, or destination, with the part being attracted and held at the proximal end by the magnets. Relative displacement in longitudinal direction of the outer and inner shafts takes place as the part reaches the destination and, consequently, the magnets are moved away from the part so that magnetic force on the part is no more influential, whereupon the part is allowed to fall under gravity down to the destination.
