Power tool with coupling mechanism for joining first and second housing portions

A power tool comprising:

• a housing including
• a first housing portion having a first outer surface,
• a second housing portion having a second outer surface, and
• a screw boss defining a bore configured to receive a fastener for coupling the first housing portion and the second housing portion together,
• a motor supported within the housing between the first housing portion and the second housing portion, the motor including an output shaft defining an axis;
• a gear assembly configured driven by the output shaft, the gear assembly including a ring gear;
• and
• an impact mechanism driven by the gear assembly, the impact mechanism including a hammer configured to impart rotational impacts on an anvil;
• wherein the screw boss is formed at a location between the ring gear and the hammer in a direction parallel to the axis.
