GY-TWR Torque Wrench Ratchet Type

Precision meets versatility with our Torque wrench series. Designed for heavy-duty industrial applications, these interchangeable head wrenches offer the flexibility to switch between open-end fittings and ratchet heads while maintaining world-class accuracy across multiple measurement scales.

Key Features

  • Multi-Scale Reading: Clearly marked scales for N.m, Lbf.Ft, Kgf.m, and Lbf.Ins.
  • Robust Construction: Engineered for industrial longevity with a comfortable, non-slip grip.
  • Precision Engineering: Low least-count (L.C) increments for highly accurate torque application.
  • Narrow Swing Arc: A tight 06° swing arc allows for efficient operation in confined spaces where movement is limited.
  • Versatile Drive Sizes: Available in a full spectrum of square drives including 3/8”, 1/2”, 3/4”, and 1”.
  • Lightweight Options: Includes specialized models, offering the same high torque capacity at a reduced weight for better portability.
