Default Torque Wrenches, do you calibrate them?

I just had my 5 year old craftsman done and it was registering 5 punds over at 80ft/lbs. So I asked to do a lower torque, 64 as this is for rod bolts, and it was 3 over. So, something to think about when everyone has there perfect special secret torquing methods.

I found out the hard way when my Hobo Fake TW snapped 2 rad bracket bolts off in a row. My old HF wrenches were nearly 20ft-lbs off. Lucky i can cal them at work as i don't know where to get them cal'd elsewhere.
But if you want trouble free torque wrenchs the old beam wrenchs are hard to beat. Beam wrenchs will keep a good cal for a long time unless dropped or bent. And sometimes its kinda nice to measure break-free torque that u can't do with most other TW's (cept maybe dial types). But beam wrenchs are difficult to use in some locations.
Caught a pair of Craftsman beam wrench on sale for ready spares now.

Also: i see a lot more Angle Torque Meters used now - claimed to be more accurate. Heck even Auto Zone sells'm cheap and they use much less tool box space than a TW.

Most torque wrenches maintain very good calibration. We, at the US NAVY shop I work in, do torque wrenches all the time. Calibrating that is. We need to due to QA/SOC/SS stuff.

all aviation shops are required by the FAA to calibrate their tq wrenches
every 6 months for that same reason.

We do teh same, and we have to cycle the wrench five times prior to use. Our aviation friends are probably the same when it comes to QA etc for safety.

We always advise that they are still calibrated. Some digital devices we have tested have been quite off.
