I made my living for 10 years with my tools. Craftsman were ok for Home use dont say they are just as good, it cost me more to use crapsman when i had to waste my time standing in line at sears when the crap broke buy quality the first time and be done. any torque wrench will become less accurate with each use most have a spring that streches with use and time. i would think being snap on is more commerically used the reason they would be inaccurate is because they were used more often than joe blow that buys a craftsman and uses it a few times. I sent my 3/8 and 1/2 snap on’s in a few times for calibration and they were rarely off and when off it was minimal
I have two Stanley’s (one that is for in·lbs, and one that goes up to 250ft·lbs) and a Craftsman that fits into the range between the other two. The Stanleys are both quality units, and I prefer them to the Craftsman.
Before I had those, I had a Snap On that I picked up at a garage sale for $20. It was nice, until my trunk leaked and it rusted.
I have a full set of snap on, and another set of c/k, both work great, and for automotive use i would consider either more than percise enough. Remember that no torque wrench is good after being dropped, and they should be calibrated annualy for percise work. I have a 6 wrench set, but only one (the 60-180 ft lb) is used on cars (usually just engines), the only reason I have a set is for my aircraft work.
