Teng tools are good quality but then so are Halfords you may have just discovered why they are nicknamed Halfrauds.Mike.

i think it all depends if you want a 3/8 drive or 1/4 drive?

why two harold? all you need is one, and maybe a adaptor for the smaller 1/4 drive.

You need to look at the spec covered and what you need it for.Mike

My aul lad used to twist his mouth as he was tightening a nut, we could tell from the angle of his lips how tight the nut was, no need for torque wrenches with him.

My aul lad used to twist his mouth as he was tightening a nut, we could tell from the angle of his lips how tight the nut was, no need for torque wrenches with him. Same here, just set your elbow and listen for 1,2, or 3 clicks. Thing is a torque wrench is only as good as the last time it was calibrated, ours are done every twelve months. What tends to happen is although the person sets it to the desired torque they always go "just that bit more" which then overloads it from what its been set at. Also when its finished with they never wind it back off to zero to take the load off the spring and if its left for a while thats bad for them. So this is now why i trust my old elbow before i trust a torque wrench.  |

I was going to get two Steve to give me a better range and also because I'm not paying, they are going to be a Christmas present from my better half  I am normally a tighten it up by hand type but just thought I would do it right for a change the truth is torque values are there for a reason. As to calibration Suki if they are looked after and not kicked about the workshop floor they should stay within tolerances for quite a while and the + or - tolerance given in the torque figures can be quite a bit which should mean even if the wrench is slightly out the fastner itself should still be within the given tolerances. Thank you all for your help and advice. |

I completely agree Harold, if your more comfortable using a torque wrench to make sure of things then it must be used. The daft thing is every nut or bolt has a specified torque setting, but I bet most people have never torqued a silencer clamp, handle bar riser or brake caliper but they will have a setting and a bloke would happily go for a ride out on his bike and not bat an eye. Good luck with whichever you choose and buy the best you can afford, you know the saying, buy cheap buy twice

I agree with all the comments above about a torque wrench's accuracy Harold. But without making a judgement on anyone's technical ability they are useful to get you used to approximately how tight any fastener should be. Most 5-6mm bolts on our bikes are probably overtightened by well-meaning owners to beyond the metal's yield point and stretched, etc. It is surprising how little effort you actually need to nip up the smaller stuff. And classic example of the valve cover bolts that I think on our bikes (they do on the CB900DOHC) tighten down to a shoulder and will go no more.......snap.

I have a 3/8 and 1/2 - mainly the latter for doing back wheel nuts up and the like.
I'm not small (albeit not a body-builder), but I was quite shocked to find that my "giving it a good heave" with a breaker bar was more than the required (100ish Nm) torque.
Also, the range point is important - the cross-over on my 2 isn't that much.
Small bolts I'm getting better at, I just don't hold the spanner all the way down and tighten it slowly.
That being said, I've nearly knackered a few bolts by relying on the Haynes torque settings, so they aren't a panacea. I reckon well worth it if you don't do enough to get your elbow in.
FWIW my mate who is a professional marine engine botherer uses Teng as his supplier of choice.

The truth is I know you can survive without a torque wrench and the truth is I have up to now, but using one is good practice. Would you fly in a aircraft where someone had guestimated how tight everything should be ? I know we all do things like just nip it up, tighten things as tight as f**k and most of the time that's fine and in all probability these are the only two settings we have pre programmed into our arms but there are many variables in between. Paul points out all fasteners have mechanical properties which are then compromised by over tightening which can lead to snapped or seized bolts, although I disagree that a torque wrench teaches you how tight tight is because you will use longer spanners for bigger fastners which makes the effort required for different bolts seem similar even though the torque settings may be very different. The truth is I don't need a torque wrench I WANT a torque wrench and you can never have too many tools, am I right |
