A method for installing a spinal implant, comprising:

• providing a pre-assembled implant, comprising:
• a rod extending in a lateral direction;
• a first implant receiver having a first rod receiving passageway extending through a first sidewall and through a second sidewall of the first implant receiver in the lateral direction, the first implant receiver having a first threaded passageway extending in a longitudinal direction and a first base portion for coupling to a first bone screw;
• a second implant receiver having a second rod receiving passageway extending through a third sidewall and a fourth sidewall of the second implant receiver in the lateral direction, the second implant receiver having a second threaded passageway extending in the longitudinal direction and a second base portion for coupling to a second bone screw;
• a first set screw having a first outside thread pattern extending along an outside circumferential surface of the first set screw and having a size and shape corresponding to a size and shape of the first threaded passageway;
• and
• a second set screw having a second outside thread pattern extending along an outside circumferential surface of the second set screw and having a size and shape corresponding to a size and shape of the second threaded passageway,
• wherein the rod extends in the lateral direction through the first and second rod receiving passageways and is constrained from moving in the longitudinal direction by the first and second rod receiving passageways;
• securing first and second bone screws to a patient;
• and
• securing the pre-assembled spinal implant to the first and second bone screws.
