Had one of the bottle cage bolts snap. it took some time to remove the remaining piece in the down tube bung. It was torqued to spec, but the bolt was alloy and the spec was for a steel bolt. I remove the other bolt and could see that it was stretched. After contacting the manufacturer I found they recommend a much lower torque spec, unfortunately they didn't specify it anywhere on the packaging of the cage. The cage was Bontrager... aka Trek.
Just glad the bung was not damaged. I've seen a seatpost bung that was cracked from over torque. Not a cheap fix.
