Ahh, that's a good point about the bolt being bent. I hadn't considered that. Next time I disassemble it to clean it, I can check. Maybe hold it against a right-angle speed square? If it is bent, is it even worth trying to straighten, or just try to find a replacement bolt? Or like you said, just leave it be.
