Two Craftsman clickers. One 1/2" drive Ft Lbs, one 1/4" drive inch lbs. I've checked them against my buddies calibrated Snap-On wrenches and they are within 2% tolerance.

 

Interestingly they also have a digitial torque measuring thing that you can put in between a regular wrench and socket and it will show you how much torque is being applied

This tool is at HF?

 

That's right.

Here's a link.

Range is not great on that thing.

Torque range: 29.5 to 147.6 ft. lbs. (40 to 200 NM)

Invest in a good tool for your $$$ machine.

 

For my money it's my calibration tool.

 

I have two craftsman, one beam and one clicker style. I use the HF digital adapter to check them for accuracy and they always seems dead on. I then check my HF wrenches and they are always accurate as well.

 

I am with you here and I have checked with them against Snap On and they are just fine. The whole thing with any clicker Torque Wrench is to make sure you back it off when you are done with a job so they don't sit with tension on them.

 

I have 8 different ones and each of them are calibrated on an annual basis due to job requirements. I have Snap on 1/4 in lbs in two different ranges, 3/8 in lbs & ft lbs and 1/2 ft lbs.,craftsman in 3/8 ft. lbs and HF in 1/4 low ft lbs and 3/8 in ft lbs. I've had them for a number of years and they always calibrate just fine.

 

3/8" and 1/2" Craftsman clickers.
