What do you think people? What are your opinions on accuracy? I need to buy either this or a 3/8" wrench, and this is WAY cheaper

way cheaper than what ?

you can buy torque wrenches at sueprcheap prob less than that

what are you going to use it for ? as that would depend on how much i would spend on a torque wrench

good reply.

i was talking to stu. feel free to go if you haven't anything useful to add.

I've seen similar systems before, using either a strain gauge or linear misalignment, but it seems to me that you'll end up less accurate and with more likelihood of drift than with a beam type torque wrench. I would steer clear of micrometer type torque wrenches though, they're susceptible to tolerance drift.

Is there any reason why a torque wrench is a must have?
I've always torqued up most bolts by feel. Haven't stripped a thread since I was 13 or so.
And nothing that I've tightened has fallen of my bike....to my knowledge.

get a 1/2 drive wrench and a 1/2 to 3/8 adaptor

i much prefer click type torque wrenches, for the tangible feedback.

also this unit looks quite bulky, and you still have to fit your sockets on the end....

what if you had to torque a bolt you couldnt see, in a noisy atmosphere? how would you tell when its done?


PS a few months ago i sold a japanese tokico torque wrench on ebay for about $100.... it was a fucking steal, and a great piece of kit,

there are certain bolts/nuts that SHOULD be torqued up, plus the piece of mind that you've done it up to factory specs leaves you feeling just that little bit more safe....well it does for me atleast.

that's not to say what you've been doing is wrong though but considering a decent torque wrench will cost you around $80-100 it's not that much really, plus when you have one you tend to torque EVERYTHING up to factory specs.

and with some bolts it's very important to do them up to factory spec and NOT MORE, otherwise shit starts breaking.

That's fine if you're taking fairings off, but have you ever pulled a head off an engine and then bolted it back on with a new gasket by feel?

There are some jobs where it's paranoid to use one, some jobs where you're better safe than sorry, and some jobs where they're absolutely necessary.

Noobs especially will benefit from a torque wrench, I showed a mate how to change the oil in his car not too long ago, and he had a lot of trouble getting the feel of how tight the sump plug had to be. A torque wrench would teach him feel without risking damage, and the number of threads I've seen on here where someone's either stripped a thread or snapped a bolt indicates that a torque wrench could be one of the best $100 investments a noob can make!

For me, a torque wrench is all about peace of mind.

+1 to sir.b about the sump plug, that's an excellent point.

I'II stick with my click type torch wrenches. I couldn't imagine use the digital addon one... way to bulky to be practical. Would restrict where it could be used.

what?

a proper digital torque wrench is the same size as a micrometer type.

What?

I'm saying that using a torque wrench for some jobs (such as tightening fairing bolts) is being paranoid, what's that got to do with the size difference between digital and micrometer wrenches?

Justin.

Actually, the other funny thing about using torque specs is that they're relatively unreliable, the best way to torque a bolt is using the torque turn method, where you torque the bolt up to some fairly low value and then give it a specified number of turns afterward. It eliminates the issues associated with thread cleanliness and also with changing coefficient of friction due to pressure or bolt coatings etc.

nothing to do with the sizes, just questioning your use of paranoid in that sentance
but now realise that im the one making mistakes... hmmm
