A spinal stabilization device includes a rod receiving member, a collet, a plug, and a bone screw. The rod receiving member defines a throughhole, a collet recess aligned with the throughhole, and a rod receiving slot offset from the throughhole. The collet is insertable into the collet recess and defines an aperture, a plug recess aligned with the aperture, and a wall portion which cooperatively defines a rod securing slot configured to selectively fix the spinal rod therein. The collet is transitionable between a first diameter, where the rod securement region defines a first diameter, and a second, larger diameter, where the rod securement region defines a second, smaller diameter. The plug is insertable within the plug recess, and transitions the collet between the first and second diameters. The bone screw includes a head portion and a threaded portion, and is insertable through the rod receiving member and the collet.
