Abstract: The invention relates to a device for screwing in magazine-fed fastening elements that comprises, inter alia, a plastic retainer (13). Between the magazine for the plastic retainers (13) and feeding elements (10) for feeding the plastic retainers (13) to the position of screwing, a picking system (16) is provided. Said picking system (16) is configured by a lever (17) that can be swiveled about an axis (19). An extension (26) that is formed on the lever arm (21) and a stop element (23) that is formed on the lever arm (20) and that can be pushed back against the force of a spring engage in the feed channel (22) alternately and sometimes also at the same time.

Abstract: A screw holder mountable on a drive unit having a tubular passage with two axially-aligned sections, each provided with locking and centering elements, such that a screw inserted into such holder can initially only penetrate until the screw head is reliably held and suspended in the first section by the locking elements. The force of the centering and locking elements upon the screw head is overcome when the apparatus is placed on the screw location and an engagement tool coupled to a drive shaft is brought into driving engagement with the screw head, which driving movement forces the locking elements radially outward in response to the axial load upon the screw head and the passage of the screw head therethrough. After the screw head passes through the first section within the tubular passage, the screw shaft is engaged by the centering elements of the second section. The centering elements of the second section are then also forced back as the head of the screw passes therethrough.

Abstract: A package for elongated parts (2) has a supporting element (1) made of a supporting strip (4) and of a tear-off covering strip (5). The supporting strip (4) has openings (6) in which the elongated parts (2) are laid, forming a row of parallel elongated parts. The package may be easily removed by tearing the covering strip (5) along perforated lines (13, 14).
