High-Accuracy Torque-Measuring Wrenches
Trust the precision of your measurements—these wrenches are accurate to ±1%. They display torque as it’s measured and the maximum torque reached. Use to determine fastener torque specifications as well as to identify the torque required to loosen tightened fasteners. To fasten to a specific value, set the desired torque—lights and an audible alarm indicate when target has been reached or exceeded. The display rotates so you can read it at any angle. Wrenches come with a calibration certificate that is traceable to NIST and includes the test measurements that confirm accuracy.
