How we checked
Retailer listings reproducing ACDelco's own spec sheet confirm 1/2 in. head, 14.8-147.5 ft-lb range, ±2%/±3% accuracy, LCD display in kg-cm/N-m/in-lb/ft-lb, buzzer + LED torque confirmation, AAA-battery power, hard-shell case, ISO 6789 compliance with calibration certificate, and 3.9 lb weight. Sources describe the unit as "just over 17 inches" long without a precise figure, so overall length (in) is left blank rather than rounded to a guessed value; the LCD's full-scale Nm bound is likewise not stated as a discrete number in any fetched source, so torque range (nm) is left blank.
