#CMT# #/CMT# The self-cutting screw (1) for screwing into a bone has at least two slots (6) which extend from the symmetry axis (S) of the screw to the generated surface of the screw head section (3). The slots are arranged at an angle of 120 degrees in relation to each other. A recess is provided in the head section in the region of the symmetry axis and is wider than the slot. In plan view, the recess is round or rectangular. #CMT#USE : #/CMT# Self-cutting screw used for screwing into bone for fastening surgical plates or similar elements. #CMT#ADVANTAGE : #/CMT# Even with the screwdriver placed at an angle higher torque for screwing in can be generated. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a first exemplary embodiment of the screw according to the invention. 1 : screw 2 : cutting section 3 : head section 4 : bearing section 6 : slots S : symmetry axis.
