I have a Craftsman torque wrench, the type where you dial in the torque by turning the handle and it clicks when you reach the desired torque. Apparently the handle is held on by 2 nuts that are on a threaded shaft that turns with the handle. The nuts came loose and now when I turn the handle nothing happens. I took the top nut and the handle off to examine it, and it looks like the handle is easy to tighten again, but the calibration is going to be all fu(ked up.

Anybody know how to calibrate one of these, or where I can take it to get it done?

It's a slightly older (12ish years) of this one (I'm sure they're mechanically identical):

If you have a friend or you are on good terms with someone that has a garage that a snap on or other tool truck comes by on a regular basis ask them if their tool man can get it done. I used wrench and snap on offered that service, but it has been a lot of years ago.

 

does that not fall under Sears lifetime warranty?

 

yea, just bring it to a snap on place... or back to sears and tell them you dont know wht happen... just remember, when you rnot sing a torqe wrench, loosen the spec to lowest possible, and that will keep it in spec next time

 

just take it back to sears they'll replace it.

 

Craftsman torque wrenches don't have a lifetime warranty. At least not now. Not sure about 12 years ago.

I have a Snap On torque wrench and the Snap On man can send them off to get the calibrated. I think it was $50 or something when I asked about it. However, not sure if he can send off non Snap On wrenches or not.

 

It really doesnt matter. If you buy 10 Snap-On TQ wrenches and send them to an independent calibrations, 5 of them will come back bad. My advice is to just borrow another TQ wrench, tighten a bolt in a vise and start adjusting on your old one till you get it close. Its just being used on cars right? If so, the calibration on it is not that important.
