SCREW all these NAILS and BOLTS

My absolute favorite way to store screws, nails and bolts is by suspending jars to the underside of a shelf.  How, do you ask?  Simply drill a hole in the metal lid and use a screw it attach it to the underside of a shelf, add contents to the jar, and reattach the jar to the lid.  Voila!  A storage solution without taking up a single square inch of shelf space.
