No. Use stainless steel with nylock. they are much easier to remove in the
future.

I'm going to install floor stiffeners (2"x4" cedar sealed 3x by S1 -
floors
are 1/2" marine plywood sealed as well) using machine SS bolts 3/8" 3", 4"
&
5" long.
Should I use any of Lctie for the nuts?
Thanks in advance
Adam
