When electric plug screw tightening

There are a lot of repairs such as electrical plug, but when the screw is tightened tightly, the round terminal was accompanied by rotation and it was tedious.
I decided to use an iron washer, but I decided to use a brass washer with good conductivity.
As a result, the terminal is stable even if it is tightened firmly.
