"so when they are screwed into the lens they become a captured screw like the factory"
Not sure how many have locked-on to this part of the discussion, the holes in the lenses are / should be smaller than the thread diameter of the screws.

  This is what I use. The head is slightly smaller diameter than a
  standard fillister/cheese head and fits the lens recess. I chuck them
  in the drill press and use a file to remove the threads from the
  portion that resides in the lens body so when they are screwed into the
  lens they become a captured screw like the factory.

  regarding Larry Westonas two sets of tail lights: one with threaded
  machine screws, the other with awooda screws.
  As in all things Pantera, we have come to accept variations in
  assembly/equipment as indicative of factory-created variety.
  What we tend to forget is these cars are FORTY+ years old and until
  just recently they have not been seen as collector-worthy cars. Thus
  repairs made by all the previous owners have not been restricted to
  aoriginalitya.
  I have received used lights from Europe with numerous aincorrecta lens
  screws. Even in metric Europe, folks often tend towards the aIall use
  what I have on-handa repair approaches.
  And here in metric-phobia USA, not many garage coffee cans have 4mm
  phillips, filiister head machine screws.
  The observation that the awood screwa lenses do not show signs of
  screw-hole cracks just tells me that set's lenses are newer than the
  other set. I suspect that set was compiled from housings/lenses some
  time after manufacture, perhaps from different sources, and the P.O.
  fell prey to the ause what I havea option for the lens screws.
  The white nylon washers with the awood screwsa are original to Carello,
  however.  They often remain attached to used lenses after the screws
  have been removed.
  Larry -  Are all four lenses marked Carello? There are reproduction
  aCarello stylea lenses on the current market - MrFiat and Hall sell
  that version.
  Also, since Jeff had to reduce the diameter of the machine screw heads
  he found I suspect what he used were in fact pan head machine screws.
  The two styles are closely similar, but the fillister style tends to
  have sharper head edges and sides; some fillister head sides are
  totally flat and parallel to the threaded shafts.
  I still do not believe any Carello lights originally came with awood
  screwsa.
