Abstract: A slip clutch includes a driven member, a spring, at least one friction plate interfacing with the driven member and an adjustment nut. The friction plate is pressed against the driven member through the combination of the spring and adjustment nut. The adjustment nut has multiple lobes and profiled surfaces between the lobes having a smaller radius from the axis of rotation of the clutch than the lobes. A hub extends along the axis through the driven member, spring, friction plate, and adjustment nut. The adjustment nut is rotationally fixed with respect to the hub and has a reduced profile to improve airflow to other components of the slip clutch.
