If we are in that situation, chances are a lot of other teams are.

The other possibility is that your team simply doesn't understand how to tighten the nuts properly. I have first-hand experience with only two broken PDB studs out of literally hundreds of boards, one caused by an unsupervised and untutored student cranking down the nut too hard, and the other caused by a cross-threaded nut being overtorqued when it was obviously stuck. I have heard of fewer than a dozen in the history of this control system, including your three.

My sample and yours have greatly different qualities. Is there any way we can get a reliable survey of PDB breakage across all of FRC?
