i have an upper deck around part of my garage i want to work on. to start i want to add some of those simpson strong ties attatched with deck screws because it's nailed together and some of the nials have worked out some, enough that i don't like that situation on a deck sitting so high. but the problem i'm having is i can't get positioned well enought to get good leverage behind the drill. i'm on a ladder and the drill is slightly over my head. i've only put a couple of the ties in and i'd say of the few i've done, i've only gotten a screw or two on each compleatly screwed in. i've tried phillip's head screws like i normally use, and some square head ones i picked up, but they seem even worse. is there a particular screw head or method i can try? thanks.
