I don't know about the total torque, but I can say they could apply great precision- in The Phantom Menace Qui-Gon manipulates the landing of a die in order to win Anakin's freedom, and does it without being obvious about it, which to me would indicate a fair bit of dexterity.

I'd probably try a long ratchet extension and some penetrating oil before hiring a Jedi for those stubborn bolts though.
