Abstract
A casing hanger and running tool system and method for rotating a casing string in a borehole include a selectively engageable connection between the casing hanger and the running tool whereby upon rotation of the casing hanger and running tool in a first direction, a length of casing may be rotated without any substantial tightening of a threaded connection between the running tool and the casing hanger, and upon rotation of the running tool in a second direction, the threaded connection between the running tool and the casing hanger may be disengaged.
