The accuracy of +/-4% of indicated value provides precise readings in both clockwise and counterclockwise operation.  Over-size dial permits easier reading, even form an angle.  Dual scale dial for quick and easy torque reading in either English or Metric values.  Memory needle dial (all wrenches through 600 Ft/Lb) remains at the highest torque value attained and allows for positive verification of torque applied, valuable to determine breakaway torque.  Electric light signal pointer (models 85446 & 20546) can be set to a desired torque value and when pointer needle reaches the preset torque value, the light is illuminated and a buzzer sounds.
