    High-Accuracy Torque-Measuring Wrenches

    Image of Product. Front orientation. Torque Wrenches. High-Accuracy Torque-Measuring Wrenches.
    Image of Attribute. Front orientation.

    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. These wrenches come with a calibration certificate, which includes test measurements that confirm accuracy.
    Torque—You can tighten fasteners that require less torque than the values listed, but the accuracy ratings apply only within the specified range.

    Image of Attribute. Front orientation.

    Trust the precision of your measurements—these wrenches are accurate to ±1%. A main pointer on the dial shows torque as it’s being applied and a memory pointer indicates the maximum torque reached. Use these wrenches to determine fastener torque specifications as well as to identify the torque required to loosen tightened fasteners. They come with a calibration certificate, which includes test measurements that confirm accuracy.
    Note: Accuracy ratings do not apply to the lower 20% of the torque range.
