Whilst the modern industry standard for spindles is 8mm square as discussed, there is a wide range of types of spindle to suit different door furniture applications. So, what if your grub screws keep falling out? On occasion, we are asked for advice from a customer whose grub screws seem to unthread themselves, and drop out of their door handles onto the floor. This can result in the door handle coming loose off the door. Why does this occur? Well, the most common cause of this is that the spindles have been installed the wrong way up, so that the grooved or slotted face is facing away from the grub screw. When this occurs, the grub screw cannot bite into the spindle, and will work itself loose over time, eventually dropping out onto the floor. The problem of grub screws falling out is irritating, but can almost always be cured very easily.
