1: ± 3% high-precision: The torque range of industrial grade torque wrenches is 5-60 Nm/3.7-44.3 lbf.ft, and adjustable torque wrenches have been fully calibrated and tested according to DIN ISO and ASME. Includes individual certificate of calibration with each set. We are full of confidence in high-quality wrenches. 2: Heavy Duty and Durable: Professional 3/8" drive torque wrench , non-slip, and corrosion-resistant. The Nm and FT-LB double scales use laser technology, which is clear and easy to read, not easy to wear, and suitable for most applications. 3: Easy to use: When the adjustable torque wrench set reaches the preset torque value, the torque wrench will make a "click" sound, which you can hear or feel, reminding you to stop applying force, so as not to damage your items due to excessive torque. When not in use, please adjust the wrench to the minimum torque value to prolong the service life of the torque wrench. 4: Precise Commissioning: Install components with calibrated precision - torque range from 5.0 to 60.0 Nm, fine-tuned to 0.5. Helps ensure that components on the bike or cars are tightened to the correct torque and that the clamping force is evenly distributed on each clamping surface. 3/8torque wrench helps prolong the life of high performance components and prevents damage from over-tightening. 5: Wide Range of Uses: Dual Direction torque wrench adjustable The blade of the torque wrench head can adjust the direction of use at any time, so that the wrench can be used in both clockwise and counter-clockwise directions. Great for stems, seat clamps, lever clamps, chain sets, rotors and headphones,automobile spark plug replacement, bicycle and motorcycle maintenance wrench, equipment installation, electrical engineering, product assembly, etc, Weight: 1.0582188576 pounds, Manufacturer: ATsafepro
