Every last screw, washer and fastener?
Maybe, but I don't think so.
Right now the DFARS specialty metal requirements for us, are applied to gears, machined parts and any raw materials we purchase which could be used to make parts that end up in Lockheed, Boeing or Govt units.
When it comes to purchasing things like motors, synchros etc. it is extremely difficult, if not impossible at this point to flow down DFARS requirements to our suppliers, their suppliers etc to cover EVERY part that goes into the product we buy.
Traditionally screws, washers and other hardware items have been bought from commercial sources and have been exempt from First Article Inspection requirements including documentation like material and finish certifications.
In fact the Military Specs and Standards governing their manufacture are being turned over to commercial control, because the Government doesn't want to keep spending the money to maintain them.
I really doubt the they will push DFARS to cover ever screw, washer and fastener simply because it wouldn't be economically feasible at this point.
