As an advisor to the local SWAT team, I was asked about keeping rifle
scopes accurate under adverse conditions.  My suggestion was to mount all
vulnerable screws with a thread locking compound and paint the exposed
surface with a protective covering, like nail polish.  My last rotor
maintenance used thread locking followed by painting the bolts with a
liquid tape widely available for protecting electrical connections.  This
followed an overnight and retightening.  The problem stems from a triad of
dissimilar metals at the contact site ( aluminum, steel and stainless).
These expand at different rates, allowing for accelerated loosening.  I
haven't drilled my heads yet.  This seems to work well.  73, Dave.
