A hand operated tool for simultaneously threading a plurality of lug nuts onto corresponding studs of an axle includes a housing having a base onto which a plurality of lug gears, each carrying a lug socket, are rotatably mounted, and a circumferential side wall carrying an annular gear having teeth meshed with teeth of the lug gears. At least one lever arm extends radially away from an outer surface of the circumferential side wall to allow all required studs to be threaded onto a vehicle axle simultaneously.

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.

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 fastening tool includes a gear train and a socket. The gear train rotates as the fastening tool moves between a non-operated position and an operated position. The socket receives a fastener at a first end of the fastener. The socket is rotatably supported to the gear assembly so that the socket rotates as the gear assembly rotates.

A press type automatic screwdriver includes a press member, a drive link, a screwdriver bit, and a screw thread pair including a screw rack and a gear engaged with the screw rack. The press member and the screwdriver bit are secured to opposite ends of the drive link, the press member and the drive link are connected by the screw thread pair, and the screw rack is resisted by the press member. The gear is secured on an end of the drive link. When the press member is pressed, the press member pushes the screw rack, the screw rack drives the gear to rotate, the gear drives the drive link to rotate, and the drive link drives the screwdriver bit to rotate.

A pocket door repair tool for removing a pocket door track and installing a new pocket door track including an illuminated powered screwdriver having a pivotable drill bit.

A ratchet wrench includes a head shell, a handle, a ratchet wheel, a driving member, a first pawl member, a second pawl member, a first biasing member, a second biasing member, a cam member, an actuating finger, and a limiting member. The limiting member including a key slot formed in one of the actuating finger and an upper major wall of the head shell, and a key which is slidably engaged in the key slot, and which is formed in the other one of the actuating finger and the upper major wall of the head shell so as to restrict angular movement of the actuating finger.
