Rotatable hand tools and fasteners

A hand tool, comprising:

• an outer housing forming an outer grip, the outer housing having a front end and a back end opposite of the front end;
• a splined socket coupled to the outer housing, the splined socket passing through the outer housing and defining a passageway through the outer housing from the front end of the outer housing to the back end of the outer housing;
• a trigger actuator coupled to the splined socket;
• and
• gearing interconnecting the trigger actuator to the splined socket, wherein the gearing increases a rotational speed of the splined socket relative to the rotational speed generated by the trigger actuator;
• wherein movement of the trigger actuator generates rotation of the splined socket, and the gearing interconnecting the trigger actuator to the splined socket increases the rotational speed of the splined socket relative to the movement of the trigger actuator.

A power tool, comprising:

• a housing defining a handle;
• a splined socket coupled to the housing, the splined socket passing through the housing and defining a passageway through the housing, the splined socket forming the passageway along a longitudinal axis passing through a center of the splined socket, the splined socket having a void that receives a fastener on a threaded shaft;
• a motor coupled to the splined socket and configured to rotate the splined socket within the housing, the motor providing a speed of rotation;
• gearing interconnecting the splined socket to the motor, wherein the gearing has a gear ratio that increases a rotational speed of the splined socket relative to the rotational speed of the motor, the gearing including a driven gear coupled to the splined socket;
• a first slot through the driven gear;
• and
• a second slot through the housing;
• wherein the first slot and second slot each have a width greater than a diameter of the splined socket and configured to facilitate interchanging the splined socket, wherein the first slot, second slot, and the void in the splined socket align to receive the fastener on the threaded shaft within the splined socket;
• wherein the handle extends parallel to the longitudinal axis.
