How to Install Ceiling Fan Junction Box Screws

Before installing a ceiling fan, you need to install the junction box. It must attach to the ceiling joist. To do this, it is often fixed with wood screws, but some junction boxes are braced to avoid sliding. Braced boxes are easily identifiable by machine screws in the attic. The best type of junction box for ceiling fans is fan-rated, which is able to support 35-70 pounds (16-32 kg).

If you’re installing the box from the attic, first remove the mounting nails. Next, remove the locknut and cable clamp from the box. Remove the box from the ceiling and install it on the wall using a brace with legs. To screw in the box, use a drill/driver with a 5/16-inch nut-driver tip. Make sure the box is attached with screws of the same size and type as the ceiling joist.

Before installing the junction box, ensure that the box you purchase is fan-rated. A fan-rated junction box may have a groove that matches the shape of a ceiling joist. To prevent this, make sure the junction box is installed correctly. If you aren’t sure, buy an inexpensive one. If you’re not sure of the size, you can purchase a large box with several screws in it. Once you’ve found the right box, you can install the fan.

If you’re replacing an outlet or light fixture, you should make sure that the screws are the right length. For electrical boxes, the screws should be one-inch long. In case they are deeper into the wall, you can use extension boxes. But don’t forget that 8-32 screws are the most common ones. They are also more powerful and are able to hold heavier light fixtures. Besides, 8-32 screws are slightly larger than 5/32. A 6-32 bit will not fit.
