A screwdriver tool including a gear ratio arranged in a handle for multiplying a rotation angle transmitted from the hand to a blade protruding from the handle. A blocking element can be rotated from a release position, in which a first handle section can be rotated relative to a second handle section for the purpose of quick-action screwing, into a blocking position, in which a blocking element secures the blade to the handle in a rotationally fixed manner. The switching between the release position and the blocking position occurs by means of a push-button arranged in the tip of the handle, which is moved back into its starting position in a spring-loaded manner after being actuated.

A tooling assembly for fastener installation has a socket body reversibly rotatable by a driving mechanism. A bore in the socket body has a first end portion and a central portion incorporating threads. A second end portion of the bore receives and engages a severable section of a frangible fastener. A pin is received in the bore and constrained from rotation by the driving mechanism. The pin has an ejection shaft with mating threads selectively receivable in the threads of the central portion of the bore. The socket body is freely rotatable with the mating threads positioned in the first end portion of the bore. Rotation of the socket body in torques the frangible fastener on a stud fracturing the severable section. Reverse rotation of the socket body engages the mating threads in the threads translating the pin. The ejection shaft ejects the severable section from the second end portion.

A single use integrated disposable rotational speed reduction assembly having a shaft assembly, a housing, a planet carrier having a gear with inward-facing gear teeth, and one or more internal gear components with gear teeth. The shaft assembly causes rotation of the planet carrier with a sun gear via engagement with the internal gear components. The rotation of the internal gear components causes rotation of the planet carrier, with a reduction of rotational speed relative to the rotation of the shaft assembly. One or more gear components can be configured to fail after a predetermined number of use cycles.

A zero distance tool for turning a fastener is disclosed. The tool may have a driver configured to receive a torsional input. The tool may also have an adapter rotatably coupled to the driver. The adapter may be configured to engage with a fastener. The tool may have a housing configured to enclose the driver and the adapter.

A nut temporary tightening device has bearing parts, a first support plate, a second support plate, and socket assemblies. Each bearing part has a cylindrical sleeve extending in an up-down direction and a flange provided at an intermediate portion of the sleeve. The first support plate has a plurality of first support holes that each support a corresponding bearing part along the outer circumference, on an upper end side, of the bearing part. The second support plate has a plurality of second support holes that each support a corresponding bearing part along the outer circumference, on a lower end side, of the bearing part. Each socket assembly has a driving shaft, a driving part, and a socket.

A screwing device for applying and/or transmitting a torque to a screw partner and for interacting with a drive torque generating means, including flat output means (6) which have an output that, can be detachably connected to the screw partner and a drive, to which a drive torque can be manually or mechanically applied, an output gearwheel (8) that can be driven by the fiat output means (6), a mechanical interface (46) for selective direct or indirect connection to the drive torque generating means for initiating the torque, a compensation unit (30) which is designed to store and process compensation data and which comprises an output gearwheel-specific torque curve and/or an output gearwheel-specific efficiency curve for calculating it with a value of an actual output torque in order to generate a value of a compensated output torque, and a data interface (36) which is designed to transmit compensation data to a drive torque generating means.

Methods and systems for increasing the efficiency of a remote wrench. The remote wrench can include a flexible plate within the tool housing or as part of the housing that is more flexible than the rigid housing in conventional remote wrenches that has been shown to limit efficiency. Additionally, a fixed support and a base can be provided that are collectively capable of being coupled to the remote wrench, preferably at the flexible plate, to increase efficiency. The remote wrench operation is therefore improved by reducing inefficiencies and providing a maximum torque output.
