Just a thought but using serrated stainless Bellville washers, over 
stainless flat washers, should keep the clamp assembly tightly 
assembled over an indefinite number of thermal cycles if properly 
torqued.  This should allow for direct burial, I think.  It's 
probably a wash on cost though.

I don't have any direct experience yet with this but is how I plan to 
address the problem shortly, FWIW.  I'd appreciate any comments on 
this idea.

Thanks,
