±4% Accuracy

Calibrated according to the ASME B107.300-2010 standard, each wrench is evaluated at three set points along its full range—20%, 60%, and 100%—with three test measurements at each set point.

Micrometer Torque Wrench Dial set to 80 ft.-lb.

Torque Setting

Maximum Expected Error

Accuracy: the maximum expected error between the torque value on the wrench’s dial and the actual force the wrench exerts on a fastener

Micrometer Design and Operation

Proper storage: To maintain calibration, store micrometer-style wrenches at their lowest setting. Tekton's 24320 should be stored at 20 in.-lb.

Clockwise Measurement

Drives in both directions and measures torque in the clockwise direction
