The factory typically uses #2 Roberts screws either 1.25 or 1.5" long. Remember your RV walls are 2" thick and some slide walls are less than that, so, driving 1 3/4" screws through a slide wall and over-torqueing "just a tad" can crush the sidewall member enough to crack the FILON skin on the slide.... So, whatever you decide to use, be careful to not penetrate the outer surface of your RV.
