Features

  • Unique geometry, patentable drive system
  • Greater drive system cross-sectional area versus Torx® and Torx Plus® drive system
  • “Full surface drive contact” with reduced drive bit/recess contact stresses versus Torx® and Torx Plus® drive systems
  • Vertical straight sidewalls
  • Reduced bit/recess wobble producing a more solid “fit”
  • Controlled gaging
  • Oversized recess lobe option

Benefits

  • Lobe geometry increased approximately 6% over Torx Plus® drive system producing:
    • Approximately 20% greater drive bit torsional strength
    • Approximately 20% greater drive system strength
    • Approximately 100% greater finite drive bit fatigue life
  • Drive size consideration may improve head strength ratio and weight reduction
  • Potential for less coating damage during installation
  • Oversized recess lobe option reduces effects of recess fill from heavy coatings
