Abstract
A rotating hanger running tool is provided allowing torque to be transmitted to a sleeve and then the casing by a set of directionally and rotationally biased dogs while bypassing a right-hand thread engaging the running tool to the casing. Upon rotating the tool in the opposite direction torque is transmitted to the right-hand thread causing the running tool and the casing to disengage.
