Nope.  Older lenses, have 5 screws.  I counted.

All lenses are 6 screw, just there are two different layouts and one style
loses a screw when 6-bitted...

Gene.. you order the flanges for the FL of the lens in question....


Remember to count the number of flange screws..... the correct number is
either 5 or 6 screws.

BTW the screwdriver to use is available through Amazon.com ... order the set
of small Phillips head screwdrivers made by WIHA.  About $20 for the set...

You need the correct mount with the right tab to identify the lens data
also.  I know, I bought a new 21 Elmarit Asph M back in '08 and it was 6 bit
coded at the factory, it would not register the lens data when mounted on my
M8, it did not bring up the correct set of frame lines (yes I know the M8
does not have frame lines for the 21, but it does have to bring up the 28/90
lines for the data to be recorded, manually selecting them with the frame
lever made the data show up).  At Photokina, I had the Leica tech guys
looked at it, and it had the wrong mount, but the correct code.  Evidently
it had the old 21 Elmarit Asph mount. The older mount does not have the
correct cam on the mount, evidently they changed it when the 6-bit coding
was applied, and my copy did not get the changed mount cam when coded at the
factory.  Had it fixed under warranty and now works just fine.  So a
universal mount with depressions cut into them will not work unless the cams
on the mount are correct
  for the lens to be coded.

Cheers,
Gene

I ran them for a while before getting genuine 6-bit adaptors at Solms. I
guess it depends on the lens, more likely to work on a slow wide than a 75mm
Summilux as the quality control may not be there. It is a reversible process
if you do not like what has changed and on some lenses only five screws will
go back in as one is under the 6-bit code.

Just saw these on eBay. You actually remove the rear plate from your lens
and replace it with one of these. Then you look up the lens code and fill in
the counter sunk depressions with (I guess) black enamel or magic marker.
The idea is that by having actual depressions to fill in, they won't wear
off like other diy solutions.
