- Poly Axial Screw: The polyaxiel screw head design allows up to 50 degree angulation. This high degree of angulation minimizes the need for rod contouring for nonlinear placement of screw heads.
- Hexa & Buttress Type: Set screw features a specially designed buttress thread which reduces the potential for cross threading and gives strong xation with screw head.
-Double Locking System: The washer in the bottom of the screw head enhances xation power of the poly screw by pressing the top of screw core.
- Self-tapping Thread: Useful to penetrate the vertebral body.
