Medical Bone Screw


DYNA-MESS has developed a special servo-electric testing machine for testing metallic bone screws according to ASTM F543. 

With a nominal force of 1 kN and a displacement of 300 mm, various test modules can be realised:

DYNA MBS 02Static torsion test

  • Torque/Angle controlled test with predefined speed
  • Adjustable fracture detection
  • Determination of yield strength, max. torque, fracture angle

    Determination of screw torque
  • Angle controlled turn in/out of bone screws with predefined speed under axial load
  • Determination of the max. driving torque

    Pull-out testDYNA MBS 01
  • Angle controlled screwing in with predefined speed
  • Displacement controlled pull-out with predefined speed
  • Adjustable fracture detection

    Determination of self-tapping properties of self-tapping medical bone screws
  • Angle controlled screwing in under increasing axial load
  • Determination of the axial force at which the self-tapping effect begins

Further information can be found in the data sheet.
