I have an Autozone OEM Tq wrench. Its about a year old...Where do you take these things to ensure they are still accurate? I dont want to take any chances when installing my heads.

Thanks,

if you know some one with a snap on torque wrench ,you can test it with that.

I use to sell craftsman tools and they sold calibration units at about 1k a piece I.e 1/4 3/8 and 1/2 were 1k per size. Outside of that.... Good luck! No one does outside of the army or like the one guy said I "think" snap on tests their own wrenches... The company that makes craftsman tq wrenches resides in Georgia, if you figure out who manufactured your wrench they may be able to help.

Here is where I go to get mine done..They are local to me but I am sure you can ship to them and they will ship back..Forty dollars for 150lbs ad Fifty dollars for a wrench up to 250lbs..Plus shipping if not local..

I have one of these. Does not calibrate, but I know where to set torque wrench to get required torque.

My local snap-on truck checks mine right on the truck .. Has a calibration tool on the truck. We have 12 of them we check about once ever 3 months.

Here's another thought that no one's mentioned - at least one of the times when I attended the NHRA Mile-High Nationals, I saw a tent/booth where they were offering torque wrench calibration services (wish I'd have known that before arriving!).

If there's a similar event near where you're at, it might be worth checking with the event organizers to see if that might be an option... (Granted, that's a "once a year, at best" option, but I thought it was worth mentioning...)

A long time ago, when I was in the Air Force, every base had a large PMEL building for tool calibration. I believe it was PMEL - Precision Measurement Equipment Laboratory.

i have 5 diff torgue wrenches all the way from a cheapo northern tool $15 one to a digital matco $550 with angle meter. depending on what im doing depends which i use.

torquing wheels i use cheapo , building a motor gets the digital , torqing other stuff on the car gets a break away type matco. i will have the digital one calibrate once every 2 years. (only 2 years old) and the others i check against the digital one. i tighten fastener to say 100ftlb indicated on the cheapo then use the digital and watch to see what the actual torque is. its actually with in a few ftlbs which is close enough for torqing wheels.

All manufacturing facilities that are ISO certified require the sevices of calbration labs.
Unfortunately most of the mfg facilities are no longer in the states thus these calibration service providers are located in industrial areas.

Locally (El Paso Tx/Juarez Mx border zone) there are several labs competing for bussines therefore costs are very competitive.
Couple months ago I purchased some used snap ons from ebay, and had them calibrated, for under the equivalent of $50....they even replaced one of the springs in one of them that was no longer within specification.

As long as you use the sevices of a certified lab, you will receive a calibration certificate for each calibrated device with worldwideq traceability, assuring acuracy, repeteability and reproducibility.

Search in the web for metrology calibration services....the std cost will be in the $35 / $50 range...

I used to check my own just to verify they were within reason(not terribly off). Simple to do.
Don't know if I still have the setup as it's been a while.
26" bar with a notch 1 " from each end and a hole to fit on the square drive with a set screw to lock it on. the notch(s) are 12"(the 1 ft of ft.lbs.) from center. With the wrench held vertically in a vice,50 lbs of weight held/in the notch would/should indicate/register 50 ft.lbs. I used it to check dial wrenches. Never tried it with clicking/beeping wrenches.

snap on tools are lifetime warranty, the guy should do it right on his truck...

If anyone goes to an IHRA or NHRA national event, you can bring your torque wrenches to the ARP trailer and see how your wrenches test on their torque meter. It'll say if they are dead on, or how far off. They won't be able to calibrate them, but it's free. They told me the SnapOn was the worst for staying in calibration. And my old Sears that I bought in 1971 was one of the best. I brought four and they all were good. Dave

they sell the small calibration boxes, it has a dial indicator with two dials on it you hook up your wrench set it and when it breaks it leaves the bottom needle at the setting while the top needle returns to 0. we have them in the hallway of the machine shop at the chemical plant I work in it's a tiny unit I can't see it costing that much

I'll look up the brand on it when I go into work tomorrow

I think they charged me $40 to calibrate mine.
