    Fastening to fiberglass panels

    Re-doing the wiring at the back of the boat. Need to mount battery charger, breaker etc.
    What is everyone using for fasteners?
    I don't fell that screws are suitable for the weight, but maybe. Rivnuts?
    I'll use nuts and bolts if they are accessible, but most locations have foam on the other side.
    The walls are 1/4" and very strong. This is an exposed view of the walls.

    I used 5200 to mount my on the go trolling motor charger, on to the back side of the live well ! I made backers from plastic decking plank, so I could remove as needed ! Waited for it to cure, then finished the mount ! It's been on for 6 yrs still going strong!

    You are over thinking/engineering things. SS pan head screws are all you need. Add some 3M 4200 or silicone to the threads if you are concerned about the screws backing out.
