Torque Wench Recommendations

Hi all,

Question is am I better off getting the BBB BTL-73 or Park TW5 because of the smaller range (im guessing that makes them more precise) and sacrificing that I wont have anything to meansure 15nm to 28nm when my other torque wrench comes into play (I'm not sure how many DIY jobs on the bike would fall in that gap as i dont want to be buying another one!).

or getting a bit more of an all rounder like the Pedros Pro Torque or Park TW-2 even though im not sure about the design.

2-14nm - http://www.wiggle.co.uk/bbb-btl-73-torqueset-torque-spanner-set/
3-15nm - http://www.evanscycles.com/products/park/tw5-small-clicker-torque-wrench-ec018758
6-30nm - http://www.wiggle.co.uk/pedros-pro-torque-wrench-20/
0-70nm - http://www.wiggle.co.uk/park-tools-torque-wrench/

I'm a bit loathed to buy one but after overrighting the headset bearing (5-6nm) seems like the sensible thing to do as my next job requires just 7.5nm also.

Also any expiriences with any of the above? both good and bad or also ones I haven't mentioned? looking to keep it under £100 but ideally as cheap as possible with out scarificing too much in the way of lifespan and ease of use.

thanks,

Dan

    Waste of money all together in my opinion.

    How did you manage to over tighten a headset bearing? Take it it was ahead? If so that should be done by feel anyway, like all preloading on bikes.

    I agree which is why I'm loathed to do it but im getting more confident about doing the work myself and less trusting of having to take it back repeatidly for the same thing going wrong when I could just buy the tool.

    only problem is that I like my weight training which doesnt bode well with not considering anything done up till I cant possibly do it up any tighter... I've ripped off and rounded a fair few bolts in my time working on cars :oops:

    think my terminilogy was off and you're right

    but in doing the job I still came across some torque ratings and i didnt feel great about my best guess tightness....

    this one?

    seems very reasonably price compared to the rest, have to look into that.... anyone else use them?

    I have two torque wrenches - one for the big jobs and one for the fiddly carbon bits - £12 and £5 on ebay - and yes I do think it is worth it to have things tightened correctly - not too tight and breaking carbon and not to loose so things fall off as you ride along happily.

    have you got any links and are they adjustable? very tempted with the teng one at the moment.

    At that price range I'm inclined to believe you would be better off using your feel and judgement than trusting a tool that possibly is way out of tolerance.

    Torque wrenches are precision tools and a reliable, accurate one is going to cost more than £5!! Any decent torque wrench will come with a calibration certificate - the cheap ones don't, so how do you know how accurate they are?
    Teng Tools are a quality brand and the one in the screw fix link looks like a nice bit of kit, and is the sort of price you need to be paying. Add a similar quality higher range one and ou should be covered. Halfords proffesional ones are decent quality and good value.
    I bought a couple of Facom Tools ones a few years ago when I used to tinker with motorbikes, but they're probably a bit more than you're looking to pay.
    I can't say I've ever bothered using one a bike though - using the appropriate size tool for the job and what my fingers tell me is tight enough is good enough for me.

    Some good advice above.

    Just to re-iterate, the calibration is the most important thing. A poorly calibrated wrench is worse than just going by feel.

    I got the Superstar one. It seems fine, I haven't over-tightened anything with it at least.

    Or you can buy one second hand with the recommendations but 20% off the price -

    The bike Branded ones are way over priced purely because there bike branded.

    Id give the Teng one a vote, i have a fair few Teng tools and they have all been solid. Add on the price of a 1/4" bit holder and a set of decent hex bits and you should be ok.

    That's the one I have and I have a halfords professional range 1/4" ratchet set, so it had all the other associated bits that i'll need in that.

    Thanks all, I bought the Teng in the end :mrgreen:

    How about this one, or is the teng still the better choice?
  • That Sealey one is very good for the money and comes with the calibration certificate. Can recommend

    Most of the time you don't need to know how accurate they are. If you are maintaining an existing bike, what you need is consistency. It doesn't matter if a required torque value is five or six Nm, what matters is that you put the part back on to a similar torque as before. So you can check the actual torque value by gradually upping the torque setting on the wrench on the object you are working on before you remove it in the first place - ie you exert pressure on the torque wrench until the torque setting is high enough to move the bolt without the wrench clicking over. That approach will also hopefully give you an idea of whether the wrench is reasonably close to calibration but either way, there probably is a decent margin for error given how many people guess, how innaccurate the guesses tend to be and how few guess related frame cracks turn up on the forums.

    Once you have that setting on the wrench, you can happily use the same value to retighten on reassembly.

    Can you check the torque for reverse threads?
  • Think so mate but will double check now

    Thanks mate. :)
  • HI

    Just to confirm that the sealey will not torque reverse threads.

    Thanks,

    Cheers Alex, I bought one, arrived today. Nice bit of kit.

    I work in a test lab where we use torque wrenches all day every working day and which are re-calibrated at 6 month intervals. There is usually no difference at cal time unless the tool has been abused by going beyond it's working range or if it's been dropped. If you look after it a good torque wrench will last many years without significant loss of accuracy.

    Why would you want to weigh a known mass?

    I would want to weigh a known mass to check that the balance read the same as I knew the mass to be.

    I just don't understand what that has to do with a torque wrench!

    Also I just noticed that the title says Torque Wench, which is a very different thing...
