if purchased from say Sears, Do torque wrenches come per calibrated?

ls1cutlas

yes they should be precalibrated. make sure you back it back down to the lowest setting before storing it and it will hold its calibration.

..and don't drop it, that will screw the calibration.

grassroots motorsports did a test on torque wrenches a few months back, the results were pretty interesting. id google it to get the results but if i remember the HF $19.99 torque wrench was the most accurate compared to the Craftsman and Mac/ Matco/ Snap On (whatever it was)

How do you go about checking a Torque wrench to see if it is still accurate?

if i had to take a SWAG, id say they used each wrench then used some type of device that measures torque on the object to see how it compared to what the wrench was set at.
anybody else have an idea on how this is done?

A calibration lab., we have one here on our station. I'm not sure if there are a lot of them in the civilain sector or not. I would imagine there would be a need for some though. I have taken mine to them here before, as they were in our hangar and set-up for that work already.

Oh, and I'm yet another owner of a Craftsman torque wrench that has broken bolts because of it's inaccuracy! Just my .2cents, don't buy one from them, THEY WILL NOT REPLACE IT. Gl.

My old shop used to take in their Snap On torque wrenches annually, and they were never off by much at all. I have a Craftsman click type and a Snap On digital tq wrench, neither of which have given me any problems at all.

Usually at the NHRA events at the racetrack, the tool suppliers have a calibration setups for any brand you have.

That's funny that you mention that, I saw a timing light comparo in one of the hot rod rags a few years ago, and the cheapo Craftsman timing light (less than $30) was the most accurate of the bunch, even more accurate than the $250+ adjustable SnapOn timing light that I had/have.

Got me a cheap one from Auto Zone. Brought it to my job and calibrated it. Was off by only 2-3%. Now it's about .5%.

I'm now going to buy several from HF and take them to my old jobs cal. lab. as you stated to insure accuracy. I don't normally skimp on tools but I can take back every torque wrench I buy from HF even, if it's 2 yrs. later. I'm replacing my Craftsman TW's with theirs now because of this. I'll just make sure that they are well calibrated and check them periodically, just like what we do with aircraft met./cal. tools. Most are required to be turned in every 6 months, used or not.
