The invention concerns a key device intended to hold a nut retainer in the radial position, when tightening the nut on an associated screw connection, characterised in that it comprises a handle (54) and a head (52) comprising a housing (56) into which a tab of the nut retainer is inserted, said tab being intended to be folded 90° on a body carrying the screw connection, after tightening of the nut, one face (58) of the head having geometry that matches a portion of the body carrying the screw connection that receives the nut, such that the tab of the nut retainer, inserted into the head of the key, is held exactly perpendicular to the outer surface of said portion of the body when the nut is tightened.

A preferred embodiment of the present invention is directed to a rotary tool and, more specifically, to a pneumatic wrench that can be used as both a standard socket wrench and as a fastening tool for setting HI-LOK-type fasteners commonly used in the aviation industry. In a preferred embodiment, the wrench comprises a handle and a rotational member connected to the handle, said rotational member configured for exerting torque about an axis of rotation in one direction only. The wrench further comprises a hole extending through the rotational member along the axis of rotation. The hole has two ends each having female threads. One end has right-hand threads and the second end has left-hand threads. The tool further comprises socket adaptors having right-hand and left-hand male threads for attaching the adaptors to the wrench. Each socket adaptor also has a through hole that aligns with the hole in the rotational member. The holes allow a hex key to be inserted through the wrench so that the wrench can be used to fasten HI-LOK fasteners. The simple design of the tool results in a wrench that is easy to use and relatively inexpensive to manufacture. A preferred embodiment of the invention further comprises a method of using the wrench.

A tool for sealing a workpiece, the workpiece comprising a first component and a second component sharing a rotation axis A, the tool comprising: a fastening head capable of engaging the first component; a first motor operationally coupled to the fastening head; a controller capable of: storing a rotation value representing rotation of the first component a predetermined desired angle around axis A; measuring movement of the first component, and controlling movement of the first motor; the tool, when the fastening head is engaged with the first component, and the second component is essentially immobilized from rotation around axis A, is configured to allow precisely sealing the workpiece by: rotating the first component in a closing direction R toward the second component, according to the rotation value and under the control of the rotation by the controller.

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.

A tool-change station includes a base, and a first tool-change member that is rotatably coupled to the base. The first tool-change member includes a first tool-engagement portion, geometrically complementary with a tool-change-engagement portion of a tool of a rotary drive.

A rotary-drive sub-assembly includes a tool and a tool retainer. The tool includes a first body and a second body. The first body includes a tool-change-engagement portion and a first threaded portion that is fixed relative to the tool-change-engagement portion. The second body includes a fastener-engagement portion. The second body is translatable relative to the first body, co-axially with the first body, and is co-axially rotationally fixed relative to the first body. The tool further includes a keeper, fixed within the first body, and a resilient member, captured between the second body and the keeper. The tool also includes a tool retainer, including a second threaded portion, configured to be threadably fastened with the first threaded portion of the first body, and a key, fixed relative to the second threaded portion.

An apparatus comprises an adjustable locking plier body. A split jaw top is joined to the plier body. The split jaw top comprises a left jaw and a right jaw. The left jaw and the right jaw are separated by a distance. A bottom jaw is joined to the plier body. The bottom jaw is generally centered on the distance, wherein the bottom jaw and the split top jaw are operative for clamping a work piece inserted between the bottom jaw and the split jaw top.

Devices, systems, and methods are provided for driving an implant and applying counter torque. For example, a driver can include a handle, a driver shaft, and a counter torque shaft, the counter torque shaft being laterally offset from the driver shaft. A distal end of each shaft can mate with a specific type of implant and/or anatomy. The shafts can be removed and replaced from the device, allowing a user to select shafts having particular lengths and/or mating tips. In use, distal ends of the shafts can be fixed or constrained relative to one another and to an implant such that the counter torque shaft cannot orbit around the driver shaft. Rotating the handle can rotate the driver shaft, driving the implant. This can cause the counter torque shaft to try to orbit around the driver shaft, but the fixed/constrained ends restrict this motion, applying the counter torque.
