My first tool box was similar to my first filing cabinet. I had a little collection going and desperately needed an organization system. One night, after trying to help the downstairs apartment install their tv and repeatedly coming up to my apartment to grab the necessary tool and head back down, I decided to get my first tool box.
Of course I labeled the individual sections on the top so that I could find everything easily. I categorized all of the small pieces: nails, screws, etc.
This is just one side of a double-sided holder, I highly recommend using tackle boxes! They are sold in the fishing section of retail stores in case you are unfamiliar. They are so great because they come in a variety of sizes and have a variety of different-sized compartments. I bought two that had small compartments and together fit in the bottom of my tool box.
The other section of my tools is contained in another holder and only used for special occasions. It contains specific hardware that is only needed in specific instances. For example, if I replace a hook or a light switch holder, I put the old one in this area so that I can access it easily if the new one breaks or becomes in some way unusable. This way, I’m not always sorting through old pieces I never use.
Although I do not yet have a tool shed or even a garage to store all of my items, the basic categories can easily be extended to fit any need: large tools, small tools/accessories and specific hardware. By keeping everything separate, while still being grouped together (and properly labeled!) you will easily find everything you need to get the job done!
