"Any of you guys ever have a fixture mounted with 4 tec screws pull out of an older deck??"
No but I've seen the whole deck come down under snow load. In some canopies they Tech screw the deck to the frame!!!. When one of the babies lets go, its like a zipper, rippppppppp and done it comes.
The light is pretty much a static load so Tech screws seem to work OK.
