A method of securing a rod to a receiver via a closure top. The receiver is configured to be used with a bone anchor and includes a pair of upright arms that define an open channel configured to receive the rod, a discontinuous helically wound receiver guide and advancement structure formed into the interior surfaces of the upright arms, and horizontally-elongated tool-engaging structures formed on the outer surface of the upright arms. The method further includes positioning the rod within the open channel of the receiver and securing the rod to the receiver by threadably advancing the closure top to secure the rod and within the receiver body of the receiver. The method further includes rotatably attaching a lower end of a tool to the receiver.
