Abstract
A bone fixation screw employs plural interleaved and axially symmetrical spiral threads. The threads are machined at the screw tip to form symmetrically disposed leading cutting edges. An interference-screw embodiment has a central axial cannula and a female hexagonal drive socket. The plural threads assist in unbiased starting and fast advance of the screw.
