Was doing a spring deep clean and during reassembly this happened. This is the first time the rings have been disassembled that I know of. I had my torque wrench set to 15 Nm, within spec, and it began getting easier instead of clicking out. The threads sheared out and I had to clean them from the screws, which are unharmed. Seems illogical to have hard SS with soft aluminum, but is there any way to repair this? The teeth are still in good order and would be a waste to discard. Thanks!

You’re cooked. New chainring and bolts, and grease the bolts next time.
I always joke that I can make anything work, once. If you don’t care about cutting/drilling the bolt out later and maybe ruining the crank, you can epoxy the bolt in there. I wouldn’t do that, but that is just about the only solution in a situation like this.
