Small parts that I use are not nuts, bolts washers and screws. I have stainless steel parts washers, nuts, and others for whirligigs. When I make one I get that container out. I haven’t made one in a while. When I make birdhouses I like to decorate with beads, copper wire, seashells and stuff, that’s in a different container. That’s how I sort.
My screws are in the box they came in and kept in a drawer. Pocket screws are with the pocket jig.
Old screws are trash.
When I did this it cleared up an entire shelf.
