Mainly for kit builders --
Because the screws are stainless steel but are threaded into aluminum,
there is a small chance of a slight galling of the threads, making it
impossible to fully tighten the screw. A bit of light oil the first
time a screw is inserted would my choice rather than a thread locking
compound. If the oil drips, you have too much on - wipe the threads
with a cloth, there will be enough remaining to do the job.
The black screws are *supposed* to be an aid in tightening, but a little
bit of extra gives that last bit of assurance.
I will repeat my caution to use a good #1 Phillips screwdriver to keep
from rounding out the screw heads. If you can see shiny spots on the
screwdriver tip, replace it with a new one.

Even though the screws may be of a stainless steel material, there is still a

anti-seize compound on these screws would be all the “thread locker” most OM’s
would need.
