The best torque wrench delivers every result with accuracy +/- 4% clockwise and +/- 6% counterclockwise because no mechanical tool can apply an exact torque every time which is why ASME B107.300 standardized these accuracy requirements to ensure safety and reliability across different industries. However, applications, even nuts or bolts, can add 1% deviation. That's why, at Precisebuilt, we test our torque wrenches to accuracy +/- 2% clockwise and +/- 6% counterclockwise in our factories.
