How big of a torque wrench were you using? For light stuff like that the best thing to use is, well I dunno what it's called, but the flexible kind that has a sweep dial. Even though my big one will go that light, it doesn't work very well, and it's too easy to over leverage a bolt/stud and break it or strip it. Go with WT on this one though, I go tight with a wrench and call it good, any more is just asking for trouble, Nate
