ABSTRACT:
A liner hanger and setting tool in which the liner hanger has an expander cone with a rotational clearance space relative to a suporting member and a low friction contacting surface for alleviating binding and frictional forces on the supporting member and where the liner hanger has spaced apart spline housings which cooperate with spline keys on a setting tool to determine rotational torque prior to and during cementing operations and where the release of the setting tool from the liner hanger can be determined prior to cementing.
