Incorporating a patented roller-release mechanism that removes 95% of internal friction, this 3/8" (9.5 mm) square drive torque wrench provides consistent operation across a 10 to 100' lbs range. It maintains 3% accuracy from 20% to 100% of full scale in both clockwise and counterclockwise directions, supported by precision bearing surfaces rated for 60,000 cycles. The 15" (38.1 cm) tool includes an external calibration port to allow for adjustments without disassembly, meeting ANSI/ASME B107.14 m and ISO6789 requirements.
