![]() ![]() ![]() The prongs of the T-nut or square part of the carriage bolt are to keep each from turning as you connect the other side. The first way you'd have machine screws/bolts, the second way you use nuts/washers to finish the mount attachment. Or, drill a shallow countersink and a hole and install carriage bolts from the top before screwing the board into the joists. If you want a "bolted" connection, drill holes and install "T-Nuts" into the board before screwing the board to the joist. ![]() If it needs to be between joists, the method you show is better, unless you are doing drywall work anyway (or have access above, as when it's an open attic, not the next floor), in which case you cut a hole (or not if it's an attic) and put that chunk of wood between the joists above the drywall, then patch it (or not if it's an attic.)įor screens, in most cases you are better off putting hooks directly into the joists and hanging the screen on chains, which allows the end of the screen to not line up with the position of the joists, yet still be solidly connected to them. Use a screw as thick as possible based on the holes in the mount, and use as many screws as you have holes for.įor most projectors (not that heavy these days), you can (depending where it needs to end up relative to the joists) put a single piece of wood that's wide enough for the projector mount screws and screwed into one joist. Now join the eye bolt to the eye screws to finish the installation. Install the small eye screws then open the lap link connector using a pair of needle-nose pliers. Drill holes in the joists for good measure. Even if the screws are a little long, they will just poke into the drywall a bit, which will be fine. Hold the board parallel to the joist then mark through the hole where the eye screw will be screwed. I used it to mount my TV to the wall.Īny wood screw that goes into the full thickness of the mounting board should be fine to hold up the projector mount. MDF will be easier to work with because it will not be warped or twisted. Since this is interior, and not a large span to tremendous weight, pine or MDF should be fine. Try to get more than an 1" into the joist. If you use a thicker board for support, you might want to bump up to 3" screws. The 2 1/2" screws should end up going into the joist about 1 1/4". I think that larger fasteners like lag bolts just aren't warranted for this project. They both have small enough heads that shouldn't stick out once they are tightened. I also like to use decking screws because of their strength and color.
