Ceiling Fan Junction Box Screw Size

Before you buy your ceiling fan or replace your existing fan, it’s a good idea to make sure you get the correct fan box screw size. Many fans are sold with the wrong fan box screw size, which can cause problems if the screws don’t fit. It’s also worth remembering that ceiling fan parts aren’t all numbered the same way. So before you start work on your ceiling fan, make sure you know the exact screw size of each part.

A ceiling fan is made up of a number of different pieces including: the blades (which will have two arms), the rotor (which will be fixed to the fan housing), bushings, bearings and ball bearings that allow the fan to rotate. The box that holds everything together is known as the fan case and its size, shape and finish vary according to the brand you buy. Be aware that some companies may label their fans differently to make them look more expensive, or to distinguish themselves from their competition. You should always buy from a reputable supplier and if you’re unsure about which fan box screw size you need, you should always ask to see the specifications.

Another reason you might want to identify your fan’s box screw size before you buy is because some companies will incorrectly use spelling mistakes when spelling their fan names. This can lead to buying a fan that doesn’t have the right number of arms or blades. A great example is the Armstrong E-series; they’ve been around for years and their fans actually spell out the brand name by using an over simplified version of the name. However despite this mistake not being too common, it’s still worth checking the screw size before you make your purchase.
