Robot (1) to tighten a series of nuts (2) pre-screwed on bolts (3) arranged in a linear or in particular 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), wherein 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) to screw the tension nut (26) onto the bolt (3).

An anti-slip torque tool that utilizes a plurality of grooves to prevent slippage and facilitate torque transfer to a fastener. The tool includes a wrench torque-tool body and an at least one engagement element. The wrench torque-tool body includes a plurality of internal sidewalls, a first base, and a second base. Further, each of the internal sidewalls includes a bracing surface. The engagement element includes a first pair of grooves and a second pair of grooves, wherein each further includes a primary cavity and a secondary cavity. The engagement element is laterally integrated into a specific sidewall to provide additional gripping action. The first pair of grooves and the second pair of grooves are positioned offset from each other, along the bracing surface of the specific sidewall. The primary cavity and the secondary cavity each traverse normal and into the bracing surface from the first base to the second base.

A tension lever includes an outer body including a top, a bottom, and a plurality of outer body sides including a first outer body side and a second outer body side opposite to and facing the first outer body side, the first outer body side having a substantially planar surface extending along a first direction and a second direction crossing the first direction, an upper first opening defined in the top and defining an upper inner body that extends along the second direction, a lower first opening defined in the bottom and defining a lower inner body that extends along the second direction, a second opening defined in the first outer body side and the second outer body side, the second opening defining a channel that extends along a third direction crossing the second direction, and a barbell including a shaft and a pair of beads at opposing ends of the shaft, the barbell being received in the second opening.

A screw bit body which allows for efficient torque force application onto a socket fastener. The screw bit body includes a plurality of laterally-bracing sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a bracing surface, and an engagement cavity. The engagement cavity creates an additional gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the bracing surface. Additionally, the engagement cavity traverses into the screw bit body from the first base to the second base. The engagement cavity is specifically positioned offset from the first lateral edge by a first distance.

A vacuum adapter for a power tool, with a bit holder extending from a front end of the power tool, is arranged to house the bit holder and to suck screws into alignment with a bit arranged inside the bit holder. The vacuum adapter includes: a connection part for connecting the vacuum adapter to the front end of the power tool such that the vacuum adapter covers the bit holder; a vacuum connection for connecting the vacuum adapter to a negative pressure source; a quick coupling for rapid disconnection of at least a part of the vacuum adapter in order to access the bit holder for exchanging bits; and a cover part arranged to cover the bit holder and that is connected to the connection part via a quick coupling and that may be separately disconnected from the power tool, leaving the connection part attached to the power tool.

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.
