The Precision, User-Friendly, Click Torque Wrench The Neiko 3/8-inch adjustable torque wrench takes the guessing out of ratcheting applications requiring precise torque levels. It ships pre-calibrated (+/- 4 percent accuracy), accurately measuring torque between 5-80 foot-pound / 6.8-108.5 Nm. Features include a dual-range pressure scale (foot-pounds or Nm), audible 'click' functionality, a unique low torque setting, and a versatile 3/8-inch drive head for sockets. Simple Torque Leveling and Use Torque levels are adjusted by aligning the rotating diamond-patterned grip with the desired level of torque indicated on the shaft. The 0-10 gradient etched into the grip allows for micrometer adjustments, and a knob locks the tension in. The 3/8-inch drive head provides compatibility with any 3/8-inch socket, while audible 'click' functionality alerts you when you reach pre-set torque values. The result is no more over-tightening of fasteners or risking of damage to components. Designed To Last Drop forged chrome vanadium steel construction ensures that this tool will withstand the rigors of time and the toughest of jobs. Add to this a chrome finish and an ABS storage case to keep away rust and corrosion and you are guaranteed an accurate, clean and shiny tool for years to come.
