Home Depot sells very nice small parts storage boxes from Dewalt for a very reasonable cost compared to other such storage boxes. The only down side is that it’s hard to get small items out of the sections, and smaller pieces can get stuck under or just migrate under the partitions. These boxes have a rounded corner at the bottom to make getting the last tiny screw out easier and are easy to lift out entirely so you don’t have to carry the whole box around if you only need one size of screws. There is a full sized insert box and another that is divided in half to make better use of the space for smaller items or items for which you don’t have as many to store. Note that DeWalt makes many kinds of storage boxes, these inserts will only fit in the 10 and 20 compartment “Pro Small Parts Organizer” I could not find them for sale on Amazon as of this writing, but I can link to them on the Home Depot site below so you know exactly what it was built for.
