A bone plating system for the internal stabilization of a fractured bone is disclosed. The system includes a bone plate having a plurality of conical plate holes tapering toward a bone contact surface and at least two bone screws for anchoring the bone plate to a bone. The screws have a conical head with a textured or structured lateral outside surface which is greater in hardness than the portion of the bone plate which is proximal to the plate holes. The present system provides positive locking between the screw heads and the plate holes.

[What is claimed is:] [1.]wherein the structured lateral outside surface of each conical screw head has a greater hardness than each plate hole surface so that insertion of the bone screws into the plate holes at other than a coaxial position still allows geometric locking to be achieved between each screw and plate hole by penetration of the respective plate hole surface by the harder structured lateral outside surface of the conical screw head.
