How to Check if Torque Screwdrivers Are Working?
How can you check that your torque screwdriver tightens terminals to the correct torque setting?
A common question from electricians who are users of torque screwdrivers. You can, of course, send tools away to be checked, but Wiha has a handy Torque QuickCheck tool to help.

I love this tool from Wiha but it’s important to point out the wiha tool can only be used to test certain torque ranges which are quite high. They need a similar tool for all their torques screwdrivers which have lower torque ranges. So Wiha can we have that as well please. I do suspect that the tool torque variations are probably less accurate at lower ranges but this is just a suspicion. Efixx please make sure that you explain this that’s a key bit of information.
Joe can it be used to check any other brands of torque screwdrivers? Fantastic video as always mate 👍❤️
Got one, I think its a useful check.

How often are you supposed to get a torque calibrated arm calibrated?
😂
I used to mock torque screwdrivers, and argue that since college I have been sensibly tightening screws without damaging them and making good long lasting connections. Then an apprentice rocked up and could put 1/4 turn on all of my screws! So it seems a calibrated right arm degrades over time too.
How do you know the torque tester is working. Is there a tester tester? And then a tester tester tester? All OTT...
Does the QuickCheck need to be sent away to be calibrated annually too? If so, wouldn't it just be easier to get the scewdriver checked?
This is a pointless waste of time and money. As for annual celebration for our MFT the NICEIC to me if I self check my MFT on a check box say every three months then that is acceptable , but if at any time there is a +_ drift then I should send it for calibration. We already self check out voltage indicator with a proving unit and nine times out of ten we only use it to prove dead , so is it really necessary to our voltage indicator calibrated every twelve months? Doesn’t matter how you look at it we are just constantly being ripped off And I do believe that the torque check thing will be expected to be calibrated every six to twelve months . For no real reason. Wile the quality of the products get lower the share holders get richer. Just my opinion but who am I to argue i’am just a humble spark who’s opinion means nothing.
Haven't seen any direction to do so. 🤔
@@seandempsey7351 calibration is very important for test equipment. Maybe not for house bashers, but us in larger industry realise the need for calibration.
@b gg well, I am paying for calibration on lots of equipment but okay.
@@TheFool2cool that’s because you’re probably using test equipment that costs in the region of £ 10.000 to 20.000 like the big things built into a large case , and you test high power generators and stuff like that. But who am I to argue i’am just a humble spark who’s opinion means nothing.
In my opinion this will be only relevant when working on older installations and some specific devices. On newer installations we will see more and more screwless connections.
Your lucky 😄
@@efixx you're* 😂 Keyboard needs calibration
I hope we see wago rcbos/affds soon. I regularly install and test commercial premises. Last high street store I done had 4x 72ways, 1x 36way, 1x12way, 1 x contactor panel with approx 20x 4way contractors. That's over 1200 "clicks" That doesn't include the bms panel or any other connections Carried out on that job. So in a job that took 2 weeks I've ¼ of the life of one of those screwdrivers at £100+ No idea how much to calibrate one of these as I haven't found a place yet that'll actually do them. Sooner wago and Schneider mate a board together, the better!
@@darylsavage119 Hager Quick Connect....😉 Neutral- and CPC-terminals are push-in for conductors up to 4mm², for larger up to 25mm² there are still screw terminals. MCBs and RCBOs are also screwless, even the busbar is just clipped in. www.hager.at/top-themen/top-aktuell/quickconnect-stecktechnik/215216.htm The problem for the UK is the rating. In the UK you got single phase supplies in domestic dwellings with 100A. We have three-phase supply, usually with 3x63A in modern installations. The rating of these parts is 63A.
@@Marcel_Germann eww hager? Yea, the 63a rating on the feed side would be an issue, most dwellings are rated to 100a but more likely an 80a fuse in DNO cutout
A couple of points. To note 1 we are know required to test RCDs at 1x only and we are expected to trust the manufacturers when they say there RCDs work correctly? 2 yet you said in this presentation that we have our MFT calibrated and we self test by shorting the probes because we don’t just assume that it is accurate.. When it comes to self checking our MFT we have a check box and we can check all the test functions on our MFT , against the check box. 3 the torque check is calibrated to 2.1Nm so can it be used to check all the settings on a torque screwdriver? If not Then we will need to have a number of these things, if your torque screwdriver is 1 to 5 Nm plus all the points in between ie 1.2 2 . 8 and so on then we will need ten or more of those torque check things and at (correction £234 . a pop ) That is just not a realistic option . It would be a lot cheaper to just throw the screwdriver in the bin and buy a new one or just get it calibrated if you think it’s not working properly. But I could be totally wrong, but who am I to argue i’am just a humble spark who’s opinion means nothing. So I don’t think I will get an answer 😂 It has just a cured to me all this calibration we are expected to have done dose this mean we are expected to have the torque/ clutch on our combi drill calibrated and the hammer function on our hammer drill. The next thing will be we have to get our claw hammer calibrated to make sure we can pull nails out and knock nails in . It’s all a load of old tosh.
Not really worth it at torque that low. If it's fifty percent out it's still only 3nm Vs 2nm
Surely if the terminal needs to be set to 3Nm and it's only on 2Nm that is a problem? 🤔
@@efixx I think if you're using a torque screwdriver you're already doing more than 80% of sparks
@@efixx I agree but what I'm saying is the amount the tool will be "out" isn't going to be anywhere near fifty percent.
For example the standard for car torque wrenches is 4 percent error to pass
I don’t rate this tool at all. So you expect me to spend money on a torque screwdriver and then the calibrator, tbh think I’ll keep using the same screwdrivers I’ve used for 16years
I know we are in the age of recycling, but do you really need to recycle videos, this is the second or third time I have seen this product on this channel
Getting new subs all the time who may not have seen it before. 😊
Hush

Meh!
How have engineers got to the point were you need a special screwdriver to tell you that you've tightened something correctly? It's madness. Teaching apprentices what feel for and look for is surely better than blindly following a torque screwdriver which can be fooled by a binding screw etc. I did my apprenticeship in the 90s when it took 4 years min to qualify. You learnt a lot in that time from good experienced engineers. Everything these days is so bumbed down. Come on. A torque screwdriver! Learn what to feel for. Is this really where we've got to! Its like baby sitting. Rant over
Never a truer word said .
Started an electrical apprenticeship in1972 never had these toys then .But then everyone had the time to show you how to do it , everyone is just in a rush now . Was giving a good piece of advice though. Tighten it up and come back to it and recheck after a month, not always practical but it’s a good idea
I used to mock them too. But for the sake of £80, I think they’re worth every penny. It just covers your ass, if you can prove every terminal was tightened with a torque screwdriver then any liability on you goes away in the event of a fire starting from a dodgy connection. It’s just insurance more than anything. Plus they’re really satisfying to use. You can get away without using one if you’re House bashing but on big commerical/industrial sites it’s a requirement to torque terminals and everything is checked, so it’s a necessity in these environments.
Don't you think we're all taking this a bit too far, testers calibrated every year, torque screwdriver calibrated, testing our testers after every step in a test, its all a bit of a much of a muchness which isn't reflected in the pay we get or the respect we get from customers, CPS, s , manufacturers and industry. Why is the onus always on us?? When are manufacturers going to actually take some responsibility for the products they produce and manufacture some decent robust fail safe products.
Its another easy money scheme. There would be plenty more to come no doubt.
I don't think it's a problem with the manufacturers, it's a problem with physics, everything degrades over time and needs adjusting. 🤔
@@efixxlook at this guy wanting more pay because he did safe isolation correctly and fully 😂
@@TheFool2cool that's not what I said at all, what i was saying is that year on year more and more responsibility is heaped on us whilst year on year our wages don't keep up with inflation or the JIB rates (which is the industry guide) don't match or compete with other trades, for instance I saw an advert the other day for an approved spark at £16p/h whilst in the same ad a mate was offered £14p/h.... 4 years at college, endless new editions and amendments.... an extra £2 an hour for all the responsibility heaped on an approved spark who literally runs a job! Plasterers, brickies, plumbers, joiners are now making more than us yet we are supposed to keep up to date with and show and have some form of log of our keeping up to date with current regs and practices while a mountain of responsibility, paperwork, certification, maintenance of certain tools is expected of us. I don't want extra money because I know how to use a proving unit, I want a fair wage for us all that reflects the time, responsibilities, and the sheer mountain of knowledge that we're expected to hold, obtain and keep up with.
Well said Ray 👍
This is silly and, quite frankly, ridiculous, unless you can use it with all of your torque drivers within range.
