I use 'anti-seize' on things that are likely to seize - inventive of me, isn't it. The product is made from finely powdered metal and high temperature grease. Works especially well on aluminum-on-aluminum threads.
There are many grades - differing by heat rating.
I use it whenever assembling mechanisms that may benefit, even though they have never seized in the past, it's insurance.
Available from Amazon.
