Description

The Tohnichi STC3-G (-BT) Digital Torque Screwdriver measures both tightening torque and rotation angle to improve fastening reliability in low-torque assembly and inspection applications. Torque-and-angle monitoring helps detect abnormalities such as double tightening and insufficient rotation caused by galling or seizure. Its slim design, high-visibility OLED display and 360-degree LED notification ring provide clear, immediate operator feedback.

• Measures and records both peak torque and final rotation angle for improved fastening control and traceability.
• Detects tightening abnormalities, including double tightening and insufficient rotation angle caused by galling or seizure.
• Selectable Tightening Mode and Inspection Mode support production fastening, re-tightening inspection and breakaway torque inspection.
• Programmable upper and lower limits for torque and angle provide automatic Pass/Fail judgment.
• Multi-color 360-degree LED ring and buzzer provide visible and audible pre-alarm, tightening-complete and OK/NG notification.
• High-visibility OLED display shows torque, angle, memory number, battery status and Bluetooth connection status.
• Reversible measurement display supports comfortable viewing in different working positions.
• Bluetooth® Version available
  • Bluetooth® GATT communication supports bidirectional connection with compatible tightening-management applications on Windows® PCs and iPad® devices.
  • Bluetooth® HOGP keyboard mode allows measurement data to be entered directly into Excel® and other electronic forms without specialized data-entry software.
• USB Type-C connection supports charging and wired serial data output to a PC.
• Stores up to 1,000 measurement records, including torque, angle and Pass/Fail results.
• Stored data can be output or deleted in batches using the onboard data-processing menu.
• Supports clockwise, counterclockwise or both-direction torque measurement and peak hold.
• Automatic memory/reset, auto-zero, auto power-off and over-torque alarm functions help simplify operation and protect the sensor.
• Three models cover torque ranges from 5 to 500 cN·m., English, and Metric equivalents
• Model-specific torque accuracy is ±1% or ±2%, depending on the measurement range; angle accuracy is ±2° + 1 digit.
• Slim, lightweight design
• Rechargeable Ni-MH battery (BP-8) provides approximately 50 hours of continuous operation with an approximate charging time of 4 hours 30 minutes.
• Calibration certificate and quick-start manual are included.
  • CSC will provide an ISO17025 calibration cert with the purchase.
