Capasitors (construction) tech.

[Arin]

I have a particular difficulty with "capacitor stud", there are too many options and I am lost :( The rest are more or less clear, but if anyone really knows the exact names for these details, I will be very grateful.

Best and thank you

CONTEXT:
In the vernier capacitor, the electrical circuit is completed from the capacitor stud, through the brass nut, through the brass washer, to the bus bar.

IMHO: ... схема замыкается через шпильку конденсатора, латунную гайку, латунную С-образную шайбу на общую шину.
