never bust a stud yet, (well, ok, i did once but that was a loooong time ago and it was half corroded with rust anyway) never bothered with a torque wrench except at TAFE when i had to, or on certain high performance engines. mainly because if you overdo the torque, the extra load imposed by the engine actually running is what causes the failure.
these things? just tighten em up in the standard "cross" pattern, a bit at a time, and once it takes some effort to get a few degrees of turn from each nut...stop.
sheesh, i seen people use torque wrenches on a DRUMKIT! now thats wanking yourself, fo sho... you TUNE drums, you dont just tighten them to a set tension... cripes...
