When I need new washers I buy aircraft quality with the faces ground flat and parallel to very tight tolerance; probably overkill but its only a few $. I get them from MSC Industrial Supply.

I see you using a die to clean the stud threads - if it's a nice new die, not the best practice. Yes, you want the threads CLEAN, butyou don't want to remove any metal as it decreases the load-bearing surface. Better to use a thread chaser, or an old, well worn die that just cuts the debris from the grooves.
