Not sure why you went with brass. Agree that copper is soft, and it corrodes, but there are thousands of old, commercial boxes like this still in service all over the country, probably all over the world.

The old boxes used brass screws, and it's just like tightening most machine parts, "enough" torque is enough, don't over tighten any connection. Have a look at any big power company installation; it's all copper. Have a look at electrical conductivity of several metals:
