Hardware Help Needed

[Tiger's Husband]

I have many screws coming loose. I have replaced some with fasteners that look right, but they quickly rust. Does anyone know where to get good replacements for a good price? I also don't know why, but many screws are coming loose under a vinyl trim that runs the length of the camper, about 18 inches from the bottom of the camper. When I tighten them, they do not snug up like they should. What is behind the siding? Will replacing with a larger screw solve the problem or create more problems in the long run? Any insight would be greatly appreciated! Thanks ahead of time.

You need to get stainless steel screws. If you don't have to have the square head ones that came on it you can get what you need in Phillips head at most any decent hardware store. Your easiest route would be the next larger size screw. You could dab a little silicone or putty on the threads to help keep them from vibrating loose.
PS my wife says I have many loose screws too!

X2 to Stainless Steel phillips head screws. Standard replacement for my Monty. Any good hardware store should have them--not requiring you to buy more than you need.

West Marine or any good Marine store has quality stainless.
