Well, and I'll go on the ledge & say for as much as I've had to torque (Sea Doo watercraft stuff all the way to old 36mm Volkswagen axle nuts) I've found that a good sense of what a diameter and pitch of bolt can handle goes a long way in at least know what's far too light & what's far to hard.

On that same ledge, I'd say that 5nm is probably sufficient for both stem clamp 4mm hex bolts that say "6nm max" on them.

I was just curious if anybody tweaked beyond that. (5nm is pretty friggin' tight on a 4mm hex bolt)
