No, the bolt is fine, the body lost the first 3 rows of threads the bolt goes into. I didn’t have the pin that holds the float flapper seated enough and it held the bowl from seating but I didn’t notice. So it wasn’t sitting flush so I kept tightening it. Tbh I wasn’t reefing on it I had a stubby ratchet and I wasn’t giving it much. But when it skipped (almost like the ratchet missed a tooth) I knew I was in trouble.
