An autoloading screwdriver apparatus is provided which includes a base; a screw cartridge received by the base; a driver supported within the base that is selectively engageable with a screw of the screw cartridge by manually displacing the driver toward a working end of the autoloading screwdriver apparatus; and a handle grip movably coupled to the base and configured to be manually displaced in a longitudinal direction toward the working end of the autoloading screwdriver apparatus to move the driver into engagement with the screw and to displace the screw to the working end of the autoloading screwdriver apparatus for presenting the screw to be screwed into a target substrate. The autoloading screwdriver apparatus may further include a control element manipulable by a user to activate rotational movement of the driver to drive the screw into the target substrate.

A robot screw-fastening device includes a nut runner that is attached to a distal end of an arm of a robot to fasten screws one by one. A screw magazine accommodates a plurality of screws to be fed to the nut runner. A magazine inserting-extracting mechanism inserts and extracts a screw retrieving position of the screw magazine to and from below the nut runner. The screw magazine includes a flat support surface with a slit-like opening that contacts with a bearing surface of each of the screws so as to support the screws in a hanging state. The slit-like opening allows an underhead section of each screw to extend therethrough so that the plurality of screws are arranged parallel to each other in a single row.

A screwdriver compact in a front-rear direction includes a motor including a stator and a rotor including a rotor shaft extending upward frontward, a switch, a pinion, a clutch operable with the pinion, a bit holder movable in the front-rear direction in front of the clutch, a gear housing accommodating the pinion and the clutch and including front and rear divided parts, a motor housing joined to the gear housing and accommodating the motor, and a resin grip joined to the motor housing and accommodating the switch. The bit holder at a rearward position causes the clutch to be connecting to transmit rotation of the rotor and at a frontward position causes the clutch to be disconnecting to transmit no rotation of the rotor.
