Scott:  The DC-10 airliner used a lot of titanium hardware in the airframe.
The bolts are NAS  6400 series (I have a NAS6404-32  48 in my hand). For the
leading edge slat (flight controls) cable pulleys the design called for a
NAS 654V1G bolt with an all metal castellated low height dry film lubed
nut. I am unaware of any special treatments required for dissimilar metal
protection. I do not remember the washer details.
Since my aircraft is not to the stage of bolting the WAFs I expect that the
WAFs are bolted together with  wet primer followed by a coat of paint.
