I asked a question in an F/class group on Facebook about whether I should grease the stainless action screws for my Panda. Let's just say the responses have been pretty well split on both sides.
So, what does everyone here think?
Any thread and every thread should be lubricated. (with something even if its just oil, grease is better)
if anything to reduce the friction of the two surfaces when tightening
Plus the added corrosion protection
And if it's alum. YES, it is not as hearty of a metal as steel and can gall
ESPECIALLY soft stuff such as 6000 series
7000 series is much better but still is Alum.
I am a mechanic that works on ATV engines (My main course of business so deal with A LOT of aluminum female threads)
I learned to grease every thread when I worked in a bike shop as a teen, small fasteners need it as it prevents many unwanted bad things happening that I won't get all technical with here.
----------------
Some people "incorrectly" believe that grease or oil will allow a fastener to loosen up easier
thinking it is the friction between the two threaded surfaces that hold the fasteners together
When it is more the torque applied to provide clamping force is what we're after.
Also grease under the head of any fastener will help once clamping force is being approached to allow the head to spin as friction free as possible

If someone wishes to use loctite instead, Loctite also provides some amount of lubrication to the threads upon initial tightening and is Still better than dry threads
