Best screws to attach WH to foam board?
Trying to seal up exterior gaps before winter. Started with the water heater that was pulling off the wall. I tried to tighten it months ago. But noticed all the screws on the right side were stripped...

I really don't think there's much stability for screws of any type to grab in any type of foam board. I can get at the backside of my WD from inside under the dinette seats. See if you can get access from inside and use either 10/24 (3/16th) stainless nuts and bolts long enoughto hold it together.
