View Full Version : How many time do you clik a torque wrench?

Iv always tightened until the right torque was achieved and then released tension and did it a second time(click it twice for a click type). A guy at my work was trying to instruct me that this method isnt correct. He said he was an aircraft mechanic previously and that he had been taught by an engineer to only reach the torque once. I don't really think it matter how many times you let it click as long as you don't keep tightening after it clicks.

Im a double clicker.

Once im all done i do a final one click triple check.

My wrench beeps and vibrates.:smoker: Once only

I think it's all in your head or whatever your habit is. Once it clicks it doesn't really matter, you're already there. With that said I'm usually a double clicker.

Technicly(sp) you should only do it once cause double clicking can change the original torque setting. Most things we torque on a car have pretty wide range of what is acceptable so a double click won't hurt.

at discount tire its required to double click the lugs. first in a star pattern then a circle. so...

They've got a meter here at work to test the calibration of torque wrenches as well as the operator, double clicking increased the torque by around 5 ft/lbs, using an extension 6-12 inches long took some of the peakiness out of the amount of torque you applied so you can be closer to what the actual setting is. Using a wrench with no extension you can hit the setting you're using if you know what you're doing, but using one made it a lot easier. When we were testing I was always within the tolerance (+-4% of the value) without one, but once I used the extension I was within 1 ft/lb of the setting every time. Keep in mind I'm not a novice when using one, I'd never used one in a manufacturing setting, but I've been using them home wise since I was a kid, YMMV.

This is the one I use but for simplicity I described the click type.

^^^^^
Same one I use works great.

I don't think I've ever single-clicked anything, even with aluminum parts.

My only complaint about it is that they need to redesign the battery end cap. Thing pops off too easily.

I hated mine. Ate battery and that damn thing would pop off.

I prefer the old school type. It was nice for convenience, and i still have it.

Now that i dont work on them everyday it sits in the box.

Im in the aviation (Marine Corps Aviation, which is governed by naval aviation) and we were always always taught to double click.

Personally I don't think it adds TQ just by feel because once you click it once you just pull/push it one more time and it clicks easily at that point. I'm sure there is some engineer out there can disprove thant means of mathematic equation, but it is what it is

It most deffinetly has been disproved.

I have the same wrench listed above and love it so far but only because of some of the other features it has like torque angle which is used so often theese days almost more so than an actual ft lb measurement at least for fasteners that require a more precise torque.

Never had that problem.

im a single clicker, but wouldnt think its a big deal to click twice

There are a couple of reasons I bought mine. The first is that it calculates angle even if you have to ratchet it. Which comes in handy when doing heads on a front wheel drive v6 or other crammed engine bays. It also goes down to 12.5ft/lbs and up to 250 so it has the widest range of torques vs other brands/style wrenches. You can use it in reverse unlike most torque wrenches. And you can change the measurement from ft/lbs to in/lbs to Nm. I also bought a snap-on version because people wont argue about the quality of snap-on tools(even thought all of the tool truck digital torque wrenches are made by the same company). If I bought a craftsman, matco, mac, etc... I would eventually hear someone complain about how that tool brand sucks when it comes to torque wrenches.
