Screws - ASTM F543

Standard specification and test methods for metallic medical bone screws


The ASTM F543 standard provides performance considerations and standard test methods for measuring mechanical properties in torsion of metallic bone screws that are implanted into bone.

The following tests are described:

  • Static torsion test
  • Determination of the driving torque
  • Pull-out test
  • Determination of the self-tapping performance of self-tapping bone screws
