Impala 6-cyl

I was rotating the tires at home. When replacing the wheels I started and snagged the lug nuts by hand. I went to torque the lug nuts to specifications (100 foot pounds) using a torque wrench. One of the right front lug nuts would not stop turning way before reaching the specified torque. As I continued to turn the wrench, the stud snapped off. One of the lugs/studs next to it also felt suspicious. I took it to the dealer and had all studs and lugs replaced on that wheel as I am afraid there may be a bad batch of studs. The parts have been saved if needed for testing. I was a mechanic in the 1960's and have been doing this work on my own and family vehicles since then. I can not recall ever snapping a stud before.
