Eliminating inaccuracies caused by hand placement, this fixed drive torque wrench utilizes a patented torsion bar design to measure the actual twist of the 1/4" (6.4 mm) square drive. It maintains 3% accuracy from 40 to 200 in-lbs in both clockwise and counterclockwise directions, supported by a roller-release mechanism that removes 95% of internal friction. Precision bearing surfaces extend the service life to 60,000 cycles, while an external calibration port allows for adjustments without disassembling the tool.

All M series meets or exceeds all applicable requirements of: ANSI / ASME B107.14' (107.14 m), GGG-W-00686C, BS6073: 1988 ISO6789 Enables the user to read the actual twist of the square drive And, since a lever principle isn't used, hand-hold position is not critical, unlike the split or bending beam competitive torque wrenches
