Sorry to hijack this thread but can someone tell me why, when all my sockets are 1/2inch I can't find a 1/2inch drive torque wrench that goes down below 28NM? My current one goes from 28-210nm but sometimes I need to go lower.. There are hundreds of 3/8 and 1/4 inch drives that do the job, and I know that I could get a converter. It just seems strange to me, or am I missing something?
What torque wrench to but for a series 3?

You need a short handle on the low torques and the mechnisms on the break type have a limited range, on the dia type the divsions would be hard to read on low torques so again the range is limited. I used to do some nuts to 400lb ft, the needle on that torque wrnech would be 20lbft wide. Buy at least 2 (I have 3, 1/4 low range, 1/2 break type mid range and 1/2 click type high range) I get mine from bootsales - the aviation grade 1/4 drive was £2 with an in-date calibration sticker. People are retiring and pleased to see it go to someone who will use it. Very few people do spanner work at home now.

Never owned a torque wrench. Probably never will. I like to think of myself as an old school safe cracker who dunt need a stethoscope.

you should be able to tell when a small nut bolt is nipped up,why spanners get longer with bolt size

He means that for very low torques in non safety critical areas, you don't need a torque wrench.
I never use a torque wrench except on engine internals, just go by feel.

I do use them now, I found that most "normal" torques in the 20-50lb ft range are fairly easy to judge, but if its big - 120lb ft like the main bearing caps on the Perkins or light as in lb-in on rocker covers or carbs its hard to judge. If more people used torque wrenches on carbs, rocker covers and British bikes there would be a lot less bent and leaking engines and carbs. Just about every rocker cover, carb and chaincase I have ever taken apart has been bowed from overtightening. Obviously not by anyone on this forum I hasten to add! But trust my word, someone is doing it.

Bit like satnav. The more you use one the less you can read the road and maps.
