I have quite a few of these kinds of shelves and racks for my drills and batteries and all of my handheld battery operated tools, I got this one especially for my drills because I have quite a few of them and I want them all stored in the same place and have their batteries charged in the same place, while trying to put this together, there are two different size screws that need to be used, all of the shorter screws are too short to be used and the nut cannot thread the screw without it stripping, I literally had to go to the hardware store and buy all new screws and nuts to put this together.. I haven't finished putting it together yet because of time constraints, but if I have another problem while putting this together with the longer screws I will report back and let you know.. I would say for the time being, if you need a cordless tool Shelf like this one, by a different one from a different manufacturer that doesn't take shortcuts
