NTD Preset Type Torque Screwdriver

• Reliable, Preset Torque Control for Precision Assembly

  The NTD Preset Torque Screwdriver ensures accurate and repeatable torque application, making it ideal for assembly work requiring a fixed torque setting. Featuring Tohnichi’s limiting mechanism, when the set torque is reached a limit is felt and user should stop applying torque.

  Key Features:

  ✅ Preset Torque Control – No external scale, ensuring a secure and tamper-proof torque setting. Requires an adjusting key and torque tester for calibration.
  ✅ Limiting Mechanism – Upon reaching the set torque, the user will sense the limit as the tool springs back slightly, indicating that turning should stop. Unlike rotary slip models, if the user continues turning, additional torque will be applied.
  ✅ High Accuracy & Durability –±3% accuracy of the set value. Built with Tohnichi’s toggle clutch torque mechanism for long-lasting precision.
  ✅ Custom Torque Setting Available – Ships without a preset torque value. Factory preset service available upon request for a nominal fee.
  ✅ Versatile Compatibility – Accepts standard 1/4″ hex root bits (sold separately).
  ✅ Auxiliary Handle (NTD500CN & NTD1000CN) – Provides extra control for higher torque applications.
  ✅ Alternative Models Available –

  • For a rotary slip mechanism that prevents over-torque, see RTD and RNTD models.
  • For an adjustable torque version, see LTD models.
  • Counterclockwise Model Available – Reverse tightening option offered upon request.
  • International Compliance – Meets ISO 6789 Type II Class E standards for global use, including the EU.
