Hey guys sorry I didn't search, but I need a quick answer and sifting through search results usually takes me longer than just asking a simple question.

I have a cup and cone, loose ball, BB with a square taper campy spindle on my peugeot fixie conversion. Bulletproof bmx cranks (budget reasons).

What is the proper tightening torque for the crank bolts? The cranks just started to get a tiny bit loose, hopefully I caught it before the cranks have been irreperably damaged. I originally tightened the bolts as tight as I could get them with a 3/8" drive wratchet wrench, but I'm guessing that's not tight enough. I have a 1/2" drive torque wrench. What's the proper torque to use this time?
