A stabilization assembly is described that stabilizes bony structures such as vertebrae. The stabilization assembly is partially formed by a poly-axial assembly which includes an anchor (500) connected to a poly axial connector assembly head (300), where the poly-axial assembly has various embodiments. The assembly may include a slide ring (800), mounted in the head and a connector (700) mounted in the slide ring. The head may have a groove for coupling with a snap ring (1600). An extension (3001) is provided with locking means for locking its tubular body to the head. The slide ring and extension permit the connector to be used to drive the anchor into bone. The snap ring provides provisional fixation of one end of the connector in the head.
