Recently received a Fogger V4 and in trying to build it, the negative post on the deck unscrewed as I was unscrewing the Phillips screw sitting on top. I put the post back in and tried to tighten it up using small pliers. No luck...as soon as I try to unscrew the Phillips, the whole post comes along with it. Here's my question... can I use something like Loctite on the post threads to hold it tight? Or is there something else that I should be doing? Thanks for your help.
