1. A method of securing a rod to a receiver via a closure top, the receiver configured to be used with a bone anchor, the method comprising:
providing the receiver comprising a receiver body having a pair of upright arms extending upwardly to define an open channel for receiving the rod, the open channel opening through a front outer face and a back outer face of the receiver body, the pair of upright arms comprising opposed interior surfaces mateable with the closure top to securely lock the rod within the open channel, side outer faces opposite the interior surfaces, and top side surfaces defining a top of the receiver body, each of the pair of upright arms comprises a horizontally-elongated upper tool-engaging groove (HEUTEG) formed on the side outer face, each of the HEUTEG being spaced a distance below the top side surface, each of the HEUTEG comprising a downwardly-facing surface and an upwardly-facing surface opposing the downwardly-facing surface, the downwardly-facing surface of each of the HEUTEG extending uninterruptedly to at least one of the front outer face or the back outer face, each of the pair of upright arms comprises a planar outwardly-facing surface formed into the side outer face below the HEUTEG so as to form a pair of parallel planar outwardly-facing surfaces;
providing the closure top;
positioning the rod within the open channel of the receiver body of the receiver; and
securing the rod to the receiver by threadably advancing the closure top against the rod and between the pair of upright arms of the receiver body, wherein the downwardly-facing surface of each of the HEUTEG are located above a top surface of the rod when the rod is secured to the receiver.
