Reduction head. All screw variants are also available as long head screws (reduction screws).
Slim and flat head design. A very firm connection to the instrument allows easy insertion of the screw.
Firm connection. The continuous connection prevents movement between the head and the shaft as well as between the screw and the instrument.
4.95 mm screw neck diameter. Lends the screw the necessary stability.
Quatro flanks. The proximal shaft section increases bone anchorage in the pedicle.
Double-lead thread. The 5 mm thread pitch facilitates rapid insertion, because the pitch of the thread is larger than in single leads threads, so per revolution the insertion depth is about twice of a single lead thread.
Cannulated and fenestrated shaft. Allows reliable application of bone cement. All screw variants are available with a solid shaft design.
Self-tapping screw tip. The distal cut on the shaft provides good initial grip and supports screw insertion.
