Systems, devices and methods are provided for locking a spinal rod in a top loading pedicle screw. In one form, the device includes a slider geometrically shaped to secure the spinal rod in the bone screw in its final resting position. Engagement pins located on the slider mate with notches located on the bone screw that both provisionally, and eventually, lock the spinal rod in the bone construct. The device replaces threaded set screw designs that have been known to incur cross threading problems. Thus, the device can also make spinal rod tightening faster and easier when compared to a threaded set screw.
