The diamond series torque wrenches are calibrated to a +/- 4% (CW) accuracy. These units are tested and proven to maintain their accuracy for 5,000 cycles at full torque capacity.


Calibration is performed by comparison with reference standards which have been calibrated by a recognized NIST-laboratory and are traceable to the National Institute of Standards and Technology. A certificate of calibration is included with all of our torque wrenches with individual traceable serial number for each unit.

100% Steel

The entire body is 100% steel and feels solid in your hand with the knurled handle’s non-slip grip. The engraved Foot-Pound and Newton Meter dual scale provides a vivid and clear reading of the measurement.


This Diamond Series torque wrench by Capri Tools features a diamond contour grip design that combines an ergonomic sure-grip and a lightweight impact resistant construction. The diamond contour grip is designed for a comfortable and steady hold. The handle is made of premium impact resistant materials which is 30% lighter than traditional torque wrench handles. Our spring loaded pull down ring and specially engineered ultra smooth torque dialing help you switch torque settings on the fly: simply pull down the ring, turn the handle, and release the ring. The positive lock mechanism secures the torque setting in place while you work. The quick release button helps you easily switch between bits and sockets. The engraved Inch-Pound/Foot-Pound and Newton Meter dual scale provides a vivid and clear reading of the measurement. Torque tolerance is calibrated at +/- 4%. Each one of our torque wrenches comes with a NIST traceable certificate of calibration, in accordance with ASME B107.300-2010 and ISO 6789:2003 standards. Each torque wrench comes with a high-image case for storage.
