If you remove the top cover of a 274N (or ARA, ARC-5)
  receiver, you see an internal shield over the tuning
capacitor.
The black screws bypass the top cover and screw
into receptacles holding this internal shield in place.
By removing just the "silver" screws, you can pull
the top cover without disturbing the internal shield.
Receivers which have been disassembled and reassembled
are often put back together with mixed screws.
