allen screws and torque

I take it allen screws (or "socket head cap
screws") and hex bolts have the same standard
torque values?

If I read the charts [1] correctly, if you find
an allen screw on your bike that takes a 4mm
allen key, then its an M5, and assuming "clean,
dry threads" with 8.8 "relative strength
marking", the maximum torque is 6Nm?

I rode my bike some 40km yesterday, and noticed
a couple of things. One was that the left
shifter and hand brake was just a bit (~1mm)
too high, while the right one, while at the
same level, was just right.

Later, I was done fixing that, I checked with
the torque wrench, and both screws fell just
a little short of the prescribed 6 and 10Nm for
M5 and M6, respectively.
