Torque wrenches are a safe move, but over-tightening gets too much blame. I've seen way more bars messed up from cross-threading during installation lol.
After stripping a set myself, the torque wrench became my best friend. The real key is starting the bolts by hand to avoid cross-threading altogether. Once they're seated right, the wrench just gives you that final peace of mind. It's a slower process but saves SO much hassle and cash down the road.
