Claim 21:
22. A powered ratcheting wrench comprising:
a main housing defining a grip portion;
a motor having a motor drive shaft;
a drive assembly coupled to the motor drive shaft and driven by the motor about a first axis;
an output assembly coupled to the drive assembly, wherein the output assembly includes a ratchet mechanism and an output member, both of which receive torque from the drive assembly, causing the output member to rotate about a second axis;
a head housing coupled to the main housing via a fastener extending through the head housing and the main housing, the head housing surrounding at least a portion of the drive assembly and at least a portion of the motor, wherein the head housing defines a first end of the wrench and the main housing defines an opposite, second end of the wrench; and
a battery pack selectively coupled to the main housing at the second end for providing power to the motor when activated,
wherein the head housing is composed of an A380 aluminum alloy resulting in a center of gravity of the wrench to be proximate the grip portion,
wherein the center of gravity is between 170 millimeters and 185 millimeters away from the first end when the battery pack is coupled to the main housing.
