Features & Benefits

  • Cannulated shaft accepts 1.25 mm diameter guide wires (threaded and non-threaded wires available).
  • Hemispherical head ensures optimal annular contact with washers and Synthes plates when screws are angled.
  • Low-profile head reduces possibility of soft tissue irritation.
  • Standard 2.5 mm hexagonal drive is compatible with screwdrivers in other commonly used Synthes sets.
  • Reverse-cutting flutes assist in screw removal.
  • Choice of thread lengths offers best fit of threads into far bone fragment, for greater interfragmentary compression.
  • Cancellous thread profile uses deep cutting threads with a large pitch to increase resistance to pullout. The large pitch also accelerates screw insertion and removal.
  • Self-drilling, self-tapping screw tip facilitates screw insertion by eliminating the need for predrilling and tapping in most cases.

Short thread
