Torque wrench
Looking to get a torque wrench. What sort of torque settings should it have for car maintenance?

I think most nuts will be under 150Nm.
The big one is the hub nuts at 290Nm

If you plan doing alot of engine work, then get a digital one. It makes it alot easier to get acurate torque quickly, and you don't want to cock
it up when torquing heads etc. cos it can be costly.

how much are torque wrenches?
i've already got one. goes from 40nM all the way up, er, much higher  don't know the range. bought it about 10 years ago when i was just
a lad. got it in halfords when i was about 16 (maybe younger)
was in 'cash generator' (a pawn shop basically) just having a look while i had an hour to kill in a very small town, and saw one for sale
at £120  thought that was a bit much

In theory you need three different torque wrenches, in practice you will get away with two or even just one.
With modern engines with angualar tightened head bolts the most important is a low range 3/8" drive torque wrench to cover 10 to 45
Then you want a half inch drive wrench covering roughly 30 to 80 nm.
The reason why you need the over lap between the ranges of the two wrenches is that torque wrenches are not accuarate at the extremes of their scales,
particularly at the low end.
You can get away without the next size up as in the rreal world anything above 80 nm is just clasified as "bloody tight".
Lidl on occaision sell very decent torque wrenches (visually identical to those sold by Machine Mart and Clarke)

Thank you very much. I haven't seen the one at Lidls' yet but i was hoping to drive by and have a look at it. If it is of the correct
torque, i'll get it along with other bits and pieces.

I've got two. One big'un and one little'un. I haven't found anything yet that those didn't do.
Actually I've also got one of the bendy wire arm type analogue torque wrenches but I don't use that much any more....
Tips for any torque wrench is zero it before and after use and stop pulling as soon as it clicks.
