A few years ago I had some surprising and aggravating bolt breakage on stems and seatpost binder bolts. I found torque specs in Zinn's manual and a few places on-line, bought a torque wrench, and an oil can, and now I have a bike that is tight but not too tight.
A torque wrench can be your friend.

> I think the concept of torquing bolts have few applications on
\r?\n> bicycles. The only ones I think might apply would be crank bolts, stem
\r?\n> bolts, regular axle nuts and possibly derailleur mounting bolts. A
\r?\n> Torque wrench was available from Schwinn as an approved tool but I never
\r?\n> attended any of the schools so I dont know what it was specified for.
\r?\n> As far as hand tightening bolts or fasteners ,studies show
\r?\n> over torquing in most cases of hand tightening.
