    even though the whole Installation is metallic I can't seem to locate in the NYC amendments where it's required

    Not sure why you're seeing that because it is not required. We have been using MC-ap for years with self-grounding receptacles and never install a bonding jumper to the box. Here are all of the NYC electrical code amendments for Article 250:

    NYC 2011 Electrical Code Technical Provisions

    ARTICLE 250
    Grounding and Bonding
    SECTION 250.52
    Subsection 250.52(A)(1) – Delete the Exception in its entirety.

The head of the screw, with or without the "don't lose the screw" washer, makes contract with the strap. The threads of the screw make good, solid contact with the box. Now, please explain how removing one of the "don't lose the screw" washers improves conductivity??
      Though I never did this with receptacles, which also need to pass the EGC onto whatever is plugged into them, I have taken this approach before with switches and had inspector shoot it down even though it sort of doesn't make any sense. But I somewhat reluctantly changed it because wording in code says what it says.

        Is NYC still on the 2011 modified code?

                        More likely tinned or nickel-plated.

                            At one point they wanted #14 for all lighting circuits. Not sure why.
