Implant ID

Had a patient come in today with a loose abutment screw on this implant #30. The abutment screw accepted a square driver. Typically when the abutment screws become loose I replace with a new abutment screw but wasn't 100% sure if this was a Nobel or something else. Any help or direction to identifying this implant so I can order the correct abutment screw is appreciated.
