The invention relates to a device (10) for setting a connecting element (100, 300) with a top-side drive structure (22, 44), comprising a feed device (12) for applying an axial force, a rotary spindle (14, 40, 68,82, 140) and a drive bit (20, 42, 60, 70, 80, 142, 242) connected to same, which has drive structures (22, 44) arranged circumferentially and at the end in a setting direction (S) in order to interlockingly cause the connecting element (100, 300) to rotate, wherein the drive bit (20, 42, 60, 70, 80, 142, 242) has an axial through-opening, and the device also comprises a suction unit (18) with which air can be suctioned out at the end side of the drive bit (20, 42, 60, 70, 80, 142, 242).

A drive guide connectable to a power tool includes a shank, a barrel, and a sleeve. The shank includes a tool coupling portion and a barrel coupling portion. The barrel is coupled to the barrel coupling portion of the shank. The barrel includes a bit coupling portion configured to couple to a tool bit. The barrel also includes a first depth indicium disposed on a surface of the barrel and a second depth indicium disposed on the surface of the barrel. The second depth indicium is circumferentially spaced about the barrel from the first depth indicium. The sleeve is disposed concentrically about and slidable along the barrel. An edge of the sleeve provides a visual indicator to determine depth based on the first and second depth indicia.

A method and apparatus comprising a structure and a connector. The structure may have a number of walls forming a channel with a first opening and a second opening. The connector may be associated with the first opening. The connector may be configured to change a size of the first opening.

A handheld guide for advancing and installing a decking fastener with an elongate track with a rail and an advancement member. The advancement member carries a pivoting pawl with an engagement surface for advancing fasteners forward through the track to an installation position with a frontmost fastener aligned with a screw guide for driving a screw through the frontmost fastener. The rail has a ramp transitioning to a cliff and a lower ledge such that the frontmost fastener is maintained forward of the cliff above the ledge in the installation position. The pawl pivots to disengage from the fasteners when the advancement member moves rearwardly along the track.

A fastener installation tool and related method are provided for installing fasteners in boards. The tool can include a feed mechanism that automatically and sequentially feeds collated fasteners to a nose assembly. The nose assembly can include a guide having an alignment projection extending downwardly from the guide, and configured to engage a board corner and/or side surface, so as to align an angled bore through which fasteners are guided with the board corner and or side surface. The nose assembly can include a magnetic element located adjacent a path on which the collated fasteners are advanced. The magnetic element can exert a magnetic force on an individual fastener, aligning it for precise entry into the angled bore. The nose assembly can include a guide pocket to positively constrain a fastener as it rotates to ensure a desired advancement trajectory. A related method of installation is provided.

A fastener including a chisel point that pre-bores a hole in a work piece to prevent damage to the work piece as the fastener advances. The fastener can include a head, a shaft and a chisel brake point formed at an end of the shaft. The chisel brake point can include first and second opposing inclined surfaces disposed at an angle of about 80° to about 150° relative to one another. A thread can begin adjacent the chisel brake point and form an extension of an inclined surface and/or a chisel edge. The chisel brake point can scrape material from a work piece while pre-boring a hole. The material can be transferred to the thread, and subsequently fed up the thread, out of the pre-bored hole. The chisel brake point can also selectively retard advancement of the fastener into the work piece. Methods of installing the fastener also are provided.

A rotary-drive sub-assembly includes a tool and a tool retainer. The tool includes a fastener-engagement portion, a first threaded portion, and a tool-change-engagement portion between the fastener-engagement portion and the first threaded portion. The tool retainer includes a body and a retaining member. The body includes a symmetry axis, a second threaded portion, configured to be threadably fastened with the first threaded portion of the tool so that the tool is rotationally anchored relative to the body of the tool retainer about the symmetry axis and is translationally anchored relative to the body of the tool retainer along the symmetry axis, and a key, fixed relative to the second threaded portion. The tool retainer further includes a retaining member that is removably coupled to the body at a fixed location.
