I.e. 1/5 of the screw radius, or 1/10 of the screw diameter. So the top layer at least should clear the head. If you are using 0.4 layers I think the first two should clear the head giving a 0.8 counterbore but the screw will site higher than that because it sits on the cone. ravin steel broadheadsWebbThis screw system was designed to immobilize the dorsal bone fragment of distal radius fracture using a palmar locking plate.
