Abstract: A screw including a sealing washer assembly and a shank which defines a screw axis and has a thread in at least a portion thereof and whose one end is provided with a head. The sealing washer assembly is disposed on the shank and includes at least one sealing washer and a reinforcing washer, said reinforcing washer having a thickness, and the sealing washer assembly having a cumulative thickness is disclosed. The sealing washer assembly is spaced, along the screw axis, at a distance from an underside of the head facing the shank, said distance being greater than the thickness of the reinforcing washer and smaller than the cumulative thickness of the sealing washer assembly.

Abstract: A tool to drive fastening elements into a substrate, with a prefastening position for a fastening element, with a driving element that drives a fastening element in the prefastening position in a fastening direction into the substrate, with a transporting element, which can he meshed with a fastening element or a strip embracing a fastening element, so as to transport the fastening element in a transporting direction into the prefastening position, wherein the driving element has a fastening element that actuates the transporting element for the transporting of the fastening element into the prefastening position, is provided.

Abstract: A strip for fastening elements, each having a shank and a head, and including a plurality of holding sections joined to each other so that each can temporarily hold a fastening element, whereby a first holding section has a receptacle for a shank of a fastening element, whereby the receptacle defines a fastening direction in which a fastening device can drive the fastening element out of the receptacle and into a substrate, and whereby the receptacle has a face opening on the head side that closes off the receptacle opposite from the fastening direction, and whereby an edge of the face opening on the head side is slanted at an acute angle with respect to the fastening direction.

Abstract: A positioning device for a hand-held setting tool (10) having an actuation switch (13) for actuating the setting tool (10), with the positioning device including a rod-shaped holder (21); a connection element (22) for the setting tool (10) arranged at an end of the holder (21), and an actuating switching device including an actuation element (24), a switching link (30) connecting an actuation element (24) to the actuation switch (13), and a safety device (40) for preventing actuation of the actuation switch (13) and having a gravity-controlled intermediate element (41) having an actuation position in which it is positioned between first controlling element (34) and second control element (35) of the switching link (30), and an interruption position (16) in which it interrupts the switching link (30).

Abstract: A holding device (10) for a fastening element (51) includes at least two gripping elements (20a, 20b) each having a clamping jaw (21, 22) provided thereon, with the clamping jaws (21, 22) engaging, in their support position (19), a shaft (52) of the fastening element (51), and with at least one clamping jaw (21, 22) having, at its free end (27) adjacent to another clamping jaw (21, 22), a recess (23, 24) for the fastening element (51) and a defining an axis (A), and a pivot element (25) for pivotally supporting at least of the clamping jaws (21, 22) on a respective griping element (20a, 20b) and having a pivot axis (S) extending substantially axial to the axis (A) defined by the recess (23, 24) of the at least one clamping jaw.

Abstract: A suspending element has a wire section (12) and a support member (11) having a pot-shaped receptacle (21) for receiving an eyelet-shaped first end (15) of the wire section (12), and a clamping element (18) for securing the eyelet-shaped first end (15) of the wire section (12) in the pot-shaped receptacle (21).

Abstract: A screw including a sealing washer assembly and a shank which defines a screw axis and has a thread in at least a portion thereof and whose one end is provided with a head. The sealing washer assembly is disposed on the shank and includes at least one sealing washer and a reinforcing washer, said reinforcing washer having a thickness, and the sealing washer assembly having a cumulative thickness is disclosed. The sealing washer assembly is spaced, along the screw axis, at a distance from an underside of the head facing the shank, said distance being greater than the thickness of the reinforcing washer and smaller than the cumulative thickness of the sealing washer assembly.

Abstract: A screw includes a transition region (12) located between the screw head and the screw stem and having its circumference formed of from three to ten truncated cones (21, 22, 23) following each other in an axial direction and surface lines of which have different inclination angles (?, ?, ?) toward the axis (A) which diminish from the head (14) in direction of the tip (13), with a first inclination angle (?) of the surface line of a truncated cone (21) located closest to the head (14) amounting to from 40° to 50°.

Abstract: A suspending element has a wire section (12) and a support member (11) having a pot-shaped receptacle (21) for receiving an eyelet-shaped first end (15) of the wire section (12), and a clamping element (18) for securing the eyelet-shaped first end (15) of the wire section (12) in the pot-shaped receptacle (21).

Abstract: A positioning device for a hand-held setting tool (10) having an actuation switch (13) for actuating the setting tool (10), with the positioning device including a rod-shaped holder (21); a connection element (22) for the setting tool (10) arranged at an end of the holder (21), and an actuating switching device including an actuation element (24), a switching link (30) connecting an actuation element (24) to the actuation switch (13), and a safety device (40) for preventing actuation of the actuation switch (13) and having a gravity-controlled intermediate element (41) having an actuation position in which it is positioned between first controlling element (34) and second control element (35) of the switching link (30), and an interruption position (16) in which it interrupts the switching link (30).
