There was a torque wrench "torque-off" in a mag and the $16 HF was +-3% of the best out there. 4% is the target for accuracy clockwise while 6% is counterclockwise. IIRC it was neck and neck with a Craftsman or a Matco. Now I have to find it....I think it was Off-road magazine? They have a digital "cube" that goes between a breaker bar and the bolt that measures the torque and beeps when its preset torque is met, it can also measure the breakaway torque. Its also used to calibrate on a static stand. I have a strange 3/8 Snap-On that is not a ratchet, just a straight torque "breaker bar". Beautiful piece, Kinda hard to use......
Here is the new HF $100 ICON compared the the $400 Snap-On 1/2 torque wrench...sorry Snap-On! ICON beat it in accuracy as well as repeatablilty, and even smaller degree of ratchet. View attachment 1715336696View attachment 1715336697
