Re: Lots of sockets
If you are fitting metal back boxes then I suggest you put silicon grease on the threads of the socket screws.
Plus one billion for this! (complete with sharks with frikken lasers!)
I learned this doing aerial installation work decades ago. It's helped me out a lot where I'm dismantling something I built maybe 10 years or more ago, and the threads are still in pristine condition even when exposed to the elements. And the stuff comes off so nicely when you need it to!
Its one of the best tech tips I will ever give.
