    Abstract: The invention pertains to the attachment of a wrenching nut to a metal conduit wherein torque forces can be applied to the conduit through the nut. An annular nut member is located upon a conduit and the conduit is radially deformed to force the conduit material into engagement with keying surfaces defined upon the nut. Conduit deformation occurs on both sides of the nut for axial positioning thereof, as well as establishing a torque transmitting relationship between the nut and conduit.
