Torque Wrench

Hey dudes.

I wish to purchase a torque wrench with allen bolt fittings for minimal wonga. Can anyone make a suggestion?

Im looking at this draper jobbie.

Draper 34570 Ratchet Torque Wrench 3/8" Square Drive: Amazon.co.uk: DIY & Tools

It can do sockets obviously, but can you bung allen key thingos on it?

Yes, you will be able to stick hex bits in it.

10 - 80 Nm is far too high for stems, seatpost clamp, chainring bolts etc.
