A screwing tool, including an elongate handle which, at each of the two ends thereof, bears a head pivotable about a pivot axis and having two torque transmission flanks in each case and has a force application flank for introducing a force in order to produce a torque on the head remote from the relevant force application flank, wherein, in a pivoting end position of the head, in which a stop of the head lies against a counter stop of the handle, a narrow side of the head functionally directed away from the stop forms an extension of the force application flank. The second head forms an extension of the force application flank and can be used as a hand grip.

A self-clamping torque adapter comprises a tool base, a central hub, a plurality of clamps, and a cam actuator mechanism. The tool base has a central axis and the central hub is rotatably coupled to the tool base and configured to rotate relative to the tool base about the central axis. The central hub comprises a torque input member configured to receive a torque input. The plurality of clamps are slidably coupled to the tool base, and configured to displace bi-directionally along a radial axis. The cam actuator mechanism couples each of the plurality of clamps to the central hub. Rotation of the central hub relative to the tool base causes the cam actuator mechanism to move each of the plurality of clamps in a radial direction.

A person anchor unit (10) for person fall safety, the person anchor unit (10) comprising connection side (12) comprising a connection surface (14) adapted for facing an anchor surface (90) comprising magnetizable material; an anchor point (20) for attaching a safety line (80); one or more permanent magnets (30) positioned at or near the connection surface ( ); and at least one test unit (40) comprising a first displacement member (42I) being displaceable between a retracted position (44) and an extended position (46), wherein the first displacement member (42I) at the extended position (46) engage the anchor surface (90); a tool connection point (50) mechanically linked to the first displacement member (42I), wherein actuation of the tool connection point (50) causes displacement of the first displacement member (42I) between the retracted position (44) and the extended position (46).

Fastening systems, fastening system installation apparatus, and methods for fastening are provided. The fastening system installation apparatus comprises a sleeve and an anvil. The sleeve comprises a first sleeve end and a second sleeve end. A sleeve cavity extends into the sleeve from the first sleeve end. The anvil is slidably received by the sleeve cavity. The anvil comprises a first anvil end, a second anvil end, and at least two portions formed by at least two channels extending from the first anvil end. The at least two portions define an anvil cavity configured to receive a fastening collar and inner surfaces of the at least two portions are configured to deform the fastening collar. The sleeve is configured to radially displace the at least two portions inward relative to the longitudinal axis responsive to forcible contact between the first anvil end and the first sleeve end.

The present invention may be used for rotating a polygonal object. A first wrench member may have a handle with two ends with a fixed jaw attached at a first end and with a cavity formed in the fixed jaw and first end. A second wrench member may be a movable jaw with a curved jaw attached to a ratcheting element. The ratcheting element may be slidably positioned in the cavity to position the curved jaw opposite the fixed jaw. The second wrench member may be constrained by the cavity and a cavity insert member to slide in said cavity about the center of an arc. The cavity insert member is positioned between a rearward wall of the cavity and the ratcheting element and retains the ratcheting element within the cavity.

A fixed adjustable wrench. The fixed adjustable wrench includes a handle having a fixed jaw and an adjustable jaw forming a gap therebetween. The adjustable jaw is slidable along a shoulder and is adapted to cooperate with the fixed jaw to secure an object within the gap. An engagement member having a first set of teeth is configured to selectively interlock with a second set of teeth of the adjustable jaw. A second end of the engagement member is operably connected to a lever that is selectively moveable between an engagement position and a disengagement position. In the engagement position, the engagement member is coupled to the adjustable jaw via an interlocking of the first set of teeth and the second set of teeth. In the disengagement position, the engagement member is disengaged from the adjustable jaw allowing selective positioning of the adjustable jaw.
