1. A power tool comprising:
an outer housing;
a drive mechanism positioned within the outer housing;
a gear case positioned within the outer housing;
a gear assembly positioned within the gear case; and
an output mechanism configured to receive torque from the drive mechanism via the gear assembly to rotate about a rotational axis,
wherein the outer housing includes a rib integral with the outer housing and extending from an inner surface of the outer housing,
wherein the rib is received in an aperture of the gear case to prevent the gear case from rotating relative to the outer housing about the rotational axis,
wherein the gear assembly includes a ring gear fixed within the gear case and a plurality of planetary gears meshed with the ring gear,
wherein the rib extends through the aperture towards the ring gear,
wherein the aperture is a first aperture, and
wherein the ring gear includes a rib extending through a second aperture in the gear case.
