I’m attempting to hang a 12.5kg mirror on plasterboard using a French cleat fixing. The studs are in the wrong place, so I’ve used three molly bolts. Unfortunately one is spinning (perhaps overtightened?). Moreover, I’m not confident that the other two are properly tight on the other side, as I don’t know what I’m looking for.
Would it be possible for me to neatly remove the bolts and replace them in the same spot with others (otherwise the mirror won’t be positioned correctly). I’m thinking of using snap toggles instead, but I don’t know if this is excessive for 12.5kg.
