The SR ExacTorq® Adjustable Torque Screwdriver is ideal for any application where you need:

  • Low torque application (20 - 100 inch-ounces or 14 - 74 cNm).
  • Single-digit torque incrementation.
  • Superior ergonomics.

These needs are common in high-precision operations such as electronics and electro-mechanical repair.

Features and Characteristics

  • Bi-directional Accuracy of +/- 6% Indicated Value from 20% to 100% of capacity.
  • Meets or exceeds ASME B107.300-2010 and ISO 6789.
  • Impervious to thrust force so the accuracy of the tool and the repeatability retain their integrity while some other tools lose theirs. 
  • Unique tri-lobe grip design for enhanced comfort and handling translates into improved operator technique and lower risk of repetitive motion injury.
  • The operator cannot over-torque. Clutch releases automatically when desired torque has been achieved.
  • Torque adjusts in single-digit increments using DigiLock Control Mechanism.  
  • Extremely lightweight yet incredibly durable.
  • Uses standard 1/4" hex bits, adapters, and sockets.
  • Anti-backlash design enhances repeatability.
  • Comes with FREE calibration certificate from our ISO/IEC 17025 Accredited Calibration Laboratory included.
