Narrative:
On apr/xa/99 I cadmium metal plated threads on a strut support. There is no specified notes sheet. I checked the engineering service order and it says to cadmium metal plate all over or optionally to electroless nickel all over. I followed the shop order but there is no note for the threads. I feel I need better instructions to process the part per the engineering service order.
