The dimensions and tolerances in this specification are applicable only to metallic bone screws described in this specification.

ASTM F543 describes four different test methods for bone screws: The determination of the torsional properties, driving torque and axial pull-out strength of medical bone screws. A self-tapping performance test needs to be performed for self-tapping medical bone screws only.
