Mike,

Do you mean (single) the end point adjustment, or the (many many) linearity 
adjustment screws?

Apparently some but not all Cosmos PTO's have linearity adjustment screws 
that accept a four flute spline wrench that measures .033 inches 
across.  Folks have reported on the list that they cut off the short arm of 
one and put it in a pin vice, then fussed with it to get it into the right 
spot.  The part numbers are:
McMaster-Carr (part #7048A11)  or
Snap-On multi spline L-Shaped wrench #MS2A.


It appears to me from a picture I have that the END POINT inductor 
adjustment screw is a slotted screw like many IF cans we have in other 
radios.  If you can't *see* the thing to get a small screw driver into it, 
you may have to make a tool by soldering or epoxy-ing a little metal 
cylinder around a jewelers screw driver tip of the right size to simulate 
the more common plastic or metal adjustment tools with a recessed metal 
blade at the tip.
