If you really need to secure something nothing in the world holds like 4 1/2 in. drywall screws. You can put them almost anywhere and as long as you use enough they hold up anything. Great for roofing, hanging pictures, reattaching the headliner in your car, plugging holes in a garden hose....anything. My grandpa always said, "If you can't caulk it, screw it....with drywall screws." I swear he fixed a 1970 Montgomery television once with drywall screws.
