A screw driving includes a housing, a motor, a spindle, a locator, a first detecting mechanism and a controller. The locator is mounted on a front end portion of the housing so as to be movable in a front-rear direction relative to the housing and configured to define a depth to which a screw is driven into a workpiece. The first detecting mechanism is configured to detect a position of the locator in the front-rear direction. The controller is configured to control driving of the motor. Rotational driving of the spindle in a forward direction is started in response to the spindle being pressed rearward, and the rotational driving of the spindle in the forward direction is stopped when the first detecting mechanism detects that the locator is disposed in a specified position rearward of a most forward position within a moving range of the locator.

A fastening system including a frame, a movement control assembly, a fastener drive assembly and a collar presenting assembly. The frame can be coupled to an outside structure, for example, with a part that is to be coupled with a fastener attached to the frame. The movement control assembly is configured to controllably move the fastener drive assembly relative to the frame and the part so as to grasp the collar of the fastener, engage the threaded pin of the fastener and to threadedly engage the two structures together. The collar presenting assembly presents a collar of a fastener to the fastener drive assembly.

A reaction washer is optimized for lock-on, optional stiction ring and for a predetermined indentation depth of bidirectional serrations for secure reaction torque transfer during initial and full actuation of respective nut or bolt heads resting on it. An optional lock-on ring embedded around the reaction socket is ergonomically actuated to latch on and off underneath the reaction washer. Axial offset of the peak stress areas away from the actuation socket edges provides for reduced actuation socket diameter and consequently for the entire tool and system remaining substantially within radial assembly limits established for prior art actuation sockets alone. A coupling unit is attached to and tightened on a power torque wrench via a clamp tool utilizing the power wrench's own torque. A hand hold groove and a lock able snap release button offset from the coupling castle snap connection contribute to safe and ergonomic operation and system peak performance.

The invention relates to a system and method for driving orthopedic bone screws. In one aspect the driver includes a powered driving rod that is configured to releasably couple with a recess in a bone screw via a threaded system for coupling and uncoupling the screw from the driving rod.

A power tool includes a housing, a motor received in the housing, an output driven by the motor, and a control system. The control system includes a rotational motion sensor configured to generate a rotational motion signal that corresponds to a rotational motion of the housing about an axis, a current sensor configured to generate a motor current signal that corresponds to an amount of current drawn by the motor, and a control circuit that is configured to receive the rotational motion signal and the motor current signal and to control operation of the motor. The control circuit is configured: (a) to determine, based on the current signal, whether a detected kickback condition is likely to be false; (b) to determine, based upon the rotational motion signal, whether an uncontrolled kickback condition has occurred; and (c) to initiate one or more protective operations upon determining that an uncontrolled kickback condition has occurred and is not likely to be false.
