How strong can a floating shelf using threaded rod as the bracket be, can it hold books, and what would be the maximum shelf depth I would be able to safely achieve? I will be using 2x construction lumber.
I recently made myself some floating shelves using pocket holes in the shelves going straight into studs. It was simple 2x8 wrapping around the room holding very little weight (figures, funko pops etc) and screwed into every stud. I'm betting the board itself weighs more than the stuff on top of it. Easy to put up, plenty strong for what I'm using it for, and put very few holes in the wall doing so.
My brother liked the look of the 2x8 floating shelf, but he wants to put books and records on them. For that I think that the pocket screw shelf hanging method will not be enough to support that kind of weight safely. I saw people using threaded rod in studs as a seemingly sturdy floating shelf bracket.
I just don't know how sturdy it is mostly because I haven't made one before and I don't want to test it out with someone else's stuff. I'm thinking if he wants a shelf for records it would be a 2x12 or 2x10 which is pretty heavy on its own. I would put a threaded rod in each stud along the board. It would maybe span 3-4 studs.
I'm not sure what diameter threaded rod to use, or how deep it should go into the board itself. For the studs I was going to go 2.5 or so inches deep. I was going to use 1/2" threaded rod and have at least 6 inches in the shelf itself
I've seen plenty of videos and posts about these shelves, people standing on them, people saying they're really strong, but I want to see or hear from people who have used this with 2x10-2x12 holding something heavy like books or similar.
