A power screw driver includes a housing with a vacuum chamber communicating with a source of sub-atmospheric pressure, a motor, a drive spindle, a screw engaging bit connected to the drive spindle, a suction nozzle surrounding and being rigidly secured to the bit, and a bit supporting sleeve having a forward end part and a rear end part. The rear end part of the bit supporting sleeve is connected to the drive spindle and extends into the vacuum chamber. The forward end part of the bit supporting sleeve in contact with the suction nozzle. At least one longitudinal internal passage extends through the bit supporting sleeve and is arranged to communicate sub-atmospheric pressure from the vacuum chamber to the suction nozzle.

A captive fastener and method of use is disclosed wherein the screw is comprised of a head and shank, and where the shank includes a radial counter bore that retains a spring biased pin. The spring may bear against a plug in the counter bore or the shank inner wall, and biases the pin outward such that it extends outside of the shank in the absence of a compressive force. The captive screw is inserted through a top panel by tilting the screw at the opening of the panel such that the pin is pushed inward into the channel formed by the counter bore (against the force of the spring). Once the pin is recessed in the screw, the screw is passed through the panel opening until the shank emerges on the other side. Once the shank pushes through the panel, the pin will emerge under the biasing of the spring to extend outward of the shank in the radial direction. The pin thus prevents the screw from disengaging with the panel. A holdout fork is applied to the shank to anchor the screw at the retracted position, which keeps the screw up right against the surface of the panel.

Robot (1) to tighten a series of nuts (2) pre-screwed on bolts (3) arranged in a curved flange connection (4), which bolts (3) project from the nuts (2) pre-screwed in substantially a nut plane (13) by a projection length (15), which robot (1) comprises a drive to move the robot (1) along the curved flange connection (4) and a tool (10) to tighten the nuts (2) with a predefined torque both connected to a support platform (6), characterized in that the tool (10) is built to screw a tension nut (26) onto the bolt (3) to elongate the bolt (3) and to tighten the pre-screwed nut (2) with a predefined torque with a tightening wheel (35), which robot (1) comprises positioning means to substantially align the axis (28) of the tension nut (26) with the axis (14) of the bolt (3) by lowering the tool (10) onto the bolt (3) in order to screw the tension nut (26) onto the bolt (3).

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.
