How to make sure steering box doesn't loosen up?

"[P]ower or manual its always the other issue, breaking them loose!"

"I've pulled out a bunch of boxes through the years where the bolts were finger tight.."

I'll bet where you have a hard time breaking them loose it is due to rust. Mine weren't rusty. On the contrary, they had absorbed the oil vapors emitted by the engine and were covered in an oily film. I'll bet that's what eventually loosened them.
